Currently, you will need to delete everything from a user that you have cached from Facebook APIs. You may continue to store data they submitted specifically to your application along with their Facebook User ID but they will no longer be authorized users. Please see http://wiki.developers.facebook.com/index.php/Storable_Information for a list of information that may be stored permanently.

If you maintain a Facebook Connect site and one of your users deactivates his or her Facebook account, you can contact that user to see if the user wants to create a new account on your site. For more information, see http://wiki.developers.facebook.com/index.php/Reclaiming_Accounts

If you deactivate your account from the "Deactivate Account" section on the Account page, your profile and all information associated with it are immediately made inaccessible to other Facebook users. What this means is that you effectively disappear from the Facebook service. However, if you want to reactivate at some point, we do save your profile information (friends, photos, interests, etc.), and your account will look just the way it did when you deactivated if you decide to reactivate it. Many users deactivate their accounts for temporary reasons and expect their information to be there when they return to the service.

If you do not think you will use Facebook again and would like your account deleted, please keep in mind that you will not be able to reactivate your account or retrieve any of the content or information you have added. If you would like your account permanently deleted with no option for recovery, log in to your account and then submit your request by clicking here.

To delete a post or story from your Wall, follow these steps:

1. Hover your mouse over the story or post in question.
2. Click the "Remove" button that appears.
3. Select "Delete" in the dialogue box.

Note that once you have deleted the content you cannot restore it.

At this time, you cannot delete all Wall posts with a single click. However, you can control the visibility of posts by others by following these steps:

1. Go to the "Profile Information" section of the Privacy Settings page.
2. Scroll down to the "Wall Posts" section. The drop-down menu will allow you to choose who can view the content that is posted to your Wall by your friends. If you want to prevent people from posting to your Wall, uncheck the box next to the "Friends may post to my Wall" option.
3. You can also control which stories appear on your Wall every time you share content. When sharing something, look for the lock icon. Clicking on it will bring up a menu that lets you choose who will be able to see your post.

It’s not currently possible to edit the name of a Page. If you would like to change your Page name, you will need to delete your Page and recreate it. The Facebook team isn't able to change Page names for you.

To delete your Page, please click on "Edit Page" and then on "Delete Page" at the top of the page.

The information fields that are available for you to write in are determined by the Page category that you selected when you first set up the Page. You aren't able to change the category of your Page after you've created it, so if you would like different fields, you'll need to delete your Page and create a new one.

In a group with more than one administrator, these requests to join may be confirmed or ignored by any admin. Also, keep in mind that users may cancel their requests to join a group at any time. If a request has been canceled or handled by another admin, the link in the email may take you to your home page or to your other new requests.

Our system automatically deletes groups once they're empty (no members). If you created the group, you can delete the group by removing all members and then yourself. Note that if you were not the first admin and creator of this group, you will not be able to delete the group unless the group creator has left it voluntarily.

Our system automatically deletes groups once they're empty (no members). If you have already left the group, you may contact another admin to request that they remove the members. Please note that if there are no current admins, all group members will have the option of taking the admin role. If the group is an open group and has no admins, you may rejoin the group from the group’s page and make yourself an admin again.

To change the order of photos in a specific album, follow the directions below:

1. Go to that album and select "Edit Photos."
2. Click on the Organize Photos tab.
3. Drag photos into the order in which you would like them to appear.
4. Click "Save Changes" when you are finished rearranging them.

The album with the most recently added photo is displayed first. To change the order of albums, upload a new photo to the album you want to be listed first. You don't have to keep the photo; you can delete it and you'll still see that album first.

You can remove one of your photos while viewing it by clicking on the "Delete This Photo" link located beneath the photo. You can also delete photos from the "Edit Photos" tab. The delete option is also underneath every thumbnail.

If you want to delete an entire album, you can do so by clicking on the "Edit Photos" tab when viewing the album and then selecting "Delete Album."

To remove the tag from a photo that someone else has uploaded and tagged you in, simply view the photo, and then choose "remove tag" at the bottom next to your name. The photo will no longer be linked to your profile. Please note that if you tag a user in a photo that you did not upload, you cannot remove or edit the tag. Only the owner of the photo and the tagged user will be able to do so.

Unfortunately, you cannot restore deleted messages.

There is no way to cancel a friend request once it has been sent.

You cannot delete a gift that you have already sent. Only the recipient can delete the gift. If the gift you sent is a public gift, you can change the privacy setting on the gift from public to private.

To see a history of all your old profile photos, just go to the Profile page and click on your current profile picture. It will bring you to an album of all your profile photos. When you are viewing your old profile pictures, you will have the option to tag them, add captions, or delete them from the album.

Any user who can see your profile can see the profile pictures you have in this album. To view someone else's old profile pictures, just click on their current profile picture while viewing their profile.

If you want to delete an old profile picture, first view the album by clicking on your current profile picture. When you are viewing the album, you should see an option for Edit Photos at the top of the page. On the edit page, you are given the option to delete any of the images, as well as to tag them or add captions. Once you delete the photo, no one will be able to see it when they view your profile picture album.

You can use Friend Lists to create different privacy levels for different groups of your friends. This allows you to selectively open more of your profile to the people closest to you. From the Profile Information section of your Privacy Settings page, clicking "Customize" will open a field for "Hide this from these people." Adding a friend or Friend List name here will hide the information in question from these people when they view your profile.

If you add a user to more than one Friend List, and those Friend Lists have conflicting privacy settings, the more restrictive of the privacy settings will always be respected.

If you enter three or more friends as an exception, you’ll have the option to create a new Friend List to group these people. You can create, edit and delete Friend Lists from your Friends page.

To delete a Friend List, first select the list from the Friends page. After making your selection, the "Delete List" option will appear at the top of the page.

Yes, you can delete a gift by clicking on 'See All' on the Gift Box and managing your gifts from that page. You can delete gifts / make public gifts private, which removes them from the Wall and makes it so that others will not be able to read the message or know who sent it.

We appreciate your concern for your child's use of our website, but unfortunately we cannot give you access to the account or take any action on the account at your request. We are generally forbidden by privacy laws against giving unauthorized access to someone who is not an account holder. Please note that all users ages 13 and older are considered authorized account holders and are included in the scope of this policy.

We encourage parents to exercise any discretion they can on their own computers and in overseeing their kids' internet use.

Please do a search for computer-based Internet control technology on your preferred search engine to discover options that you may wish to pursue.

Please also talk to your kids, educate them about internet safety, and ask them to use our extensive privacy settings.

Facebook requires its users to be at least 13 years old before they can create an account. Providing false information to create an account is a violation of our Statement of Rights and Responsibilities.

Applicable laws may give parents the right to access personal information their child has provided before Facebook follows its policy of promptly deleting such accounts. If you are aware of your underage child having an account on Facebook, you can show them how to delete their account by having them log into their profile and following this link.

If you would like to report an underage user (under 13 years of age), please do so here. We will promptly delete the account of any underage user that is reported to us through this form.

Alternatively, you can submit a request to Facebook here. Please be aware that you will be required to submit a notarized statement declaring your rights as a parent or guardian immediately upon using this form.

If you would like to remove a friend, navigate to the person’s profile and click the "Remove from Friends" link at the bottom of the page. If you select this option, you will be removed from the person's Friends List as well. You will need to repeat the friend confirmation process if you wish to be friends with this person again.

You can remove an application you have authorized to your account by clicking on the "Applications" button at the left end of the Chat bar at the bottom of any Facebook page.

It is possible that this person removed the content from your profile before you were able to view it. Unfortunately, there is no way for you to view content after it has been deleted.

Facebook has determined that you were sending messages at a rate that is likely to be abusive. Note that these blocks can last anywhere from a few hours to a few days. Unfortunately, we cannot lift the block for you.

When you are allowed to resume sending messages, keep in mind that it’s possible to run into a block based on how many messages you send and how fast you send them. It’s also possible to be blocked when either starting a new message thread or replying to a message. Lastly, deleting old messages will not allow you to send more messages. In the future, please proceed with caution to avoid hitting the limit again. Please be aware that further abuse of such features can result in your account being permanently disabled.

When users post content to an open forum on the site (i.e., Facebook Pages, the "Questions and Answers from Users" section of the Help Center, "Open" Groups), this material may also be indexed by search engines.

Unfortunately, Facebook does not have control over content that has already been indexed and cached in search engines. If you no longer wish for this content to appear in search engine results, please delete it from the forum to which you originally posted it. Doing so will render the link that appears in search engine results invalid.

We want Facebook to remain an environment where people can connect and share comfortably. Cyberbullying is defined as the use of any new technology to harass or intimidate someone and is considered to be abusive behavior from minor to minor, while cyberharassment typically involves adults. There are steps you can take to prevent this kind of behavior if it occurs.

Accept Friend Requests Safely

In order to prevent harassment from strangers, be careful to accept friend requests only from people you know in real life. Also, remember to report any messages or profiles that look suspicious. Facebook is based on a real-name culture, and fake profiles are regularly disabled when they're reported to us. Please also keep in mind that only confirmed friends can post to your Wall or contact you via Facebook Chat, so if you're worried that someone will make inappropriate posts or send offensive messages, just ignore that person's friend request.

Use the "Block" Feature to Stop Abusive Behavior

A block prevents specific people from viewing your profile. When you block people, any ties you currently have with them will be broken, and these people won't be able to contact you through Facebook. If you receive inappropriate or abusive communication, you can block the person by listing his or her name in the "Block People" box at the bottom of your Privacy Settings page. You can visit this page at any time by hovering your mouse over the "Settings" link at the top of any Facebook page and selecting the "Privacy Settings" option from the drop-down menu that appears.

Report Abusive Behavior Directly to Facebook

The most efficient way to report abuse is to do it in the same place it occurs on Facebook. For example, if you receive a harassing message in your Inbox, you can report the message by clicking on the "Report" link next to the sender's name as you are reading the message. If you receive a harassing message from a person who is a Facebook friend of yours, you should remove the person as a friend and report the message. Reporting the message as harassing will automatically add this person to your Block list. You can also use the "Report/Block person" link that appears at the bottom of the abusive user's profile. If you learn that someone is continuing to make abusive comments about you even after you've blocked them, you can ask a friend to report that person on your behalf. Reports are confidential and the user being reported does not know that they have been reported. After a report is submitted, we will investigate the issue and make a determination as to whether or not the content should remain on the site based on our Terms of Use. A Facebook administrator looks into each report thoroughly in order to decide the appropriate course of action.

Restrict Privacy Settings

To restrict the amount of information that potential bullies may have access to, customize your privacy settings so that certain people can't access information like your Wall, photos, or profile. You can also change your privacy settings if you are uncomfortable being found in searches or having your profile viewed publicly. Privacy on Facebook is controlled primarily from the Privacy Settings page. You can visit this page at any time by hovering your mouse over the "Settings" link at the top of any page of Facebook and selecting the "Privacy Settings" option from the drop-down menu that appears.

Respond to Abusers in the Right Way

Cyberbullies often seek a reaction from the people they harass. When they fail to get one, they often give up gradually. Rather than responding to a bully via Inbox, a Wall post, or Facebook Chat, you can delete offensive posts from your Wall or messages from your Inbox and then use the "Block" or "Report" functions to resolve the issue safely. To delete an offensive Wall post, hover over the post in question, click the "Remove" button that appears, and select "Delete" in the dialogue box. To delete a message from Inbox, simply click the "Delete" button at the top of the message. Only confirmed friends can post to your Wall or send you a message through Chat. If you are receiving posts and Chat messages you don't like, you should consider removing the sender from your friends list.

Some advertisements that run on third-party applications link to services that ask for your cell phone number and subsequently send text messages to your phone. While Facebook is not responsible for these advertisements, we recommend that you send a text message containing the word "STOP" (without the quotation marks) to the number from which you're receiving the messages in order to cancel the service.

You may report an application containing these advertisements to its developer(s) and to Facebook by clicking on the "Report" link that appears in the lower left corner of any page within the application. Unfortunately, we have no control over your mobile service. We suggest you contact your mobile provider and explain the situation to them.

You can view your current email address and add or delete addresses from the Settings tab of the Account Settings page. Your Facebook email notifications will only be sent to the address you designate as your "Contact Email," so be sure this information is accurate.

To change your contact email, just click the "change" link next to Email. Select any other email address you have listed on your account and click the "Change Contact Email" button to finish.

If you would like to add another email address to your account, just enter that new address in the open field next to "New Email." Once you confirm the address, you can go back and set it as your contact email.

It is possible that this person removed the content from your profile before you were able to view it. Unfortunately, there is no way for you to view content after it has been deleted.

For any content that you can edit (e.g., photo albums, videos, or notes), you can retroactively change the Publisher Control setting by finding the content you wish to edit and then changing the privacy setting.

For content that can't be edited (e.g., status updates or links), you cannot change the Publisher Control after you click "Share." Instead, you can delete the content from your Wall, which will remove it from your friends' home pages. To delete a post, hover over it on your Wall and click the "Remove" button. You can then republish the same content with the correct privacy controls.

Note that retroactive steps you take to change the setting or remove the content won’t prevent any further distribution off of Facebook that may result from the prior privacy setting enabling others to have access to and share the content.

If your account has been deleted, please visit the Help Center which offers a process to get your account back up and running. Once your account is re-enabled, please provide details using the Developer Help Contact Form and we will be happy to restore your administrative access.
