This from facebook:
If you are being harassed on Facebook, you can put a stop to it. Your profile is under your control, not the control of people who post to your wall. Here are a few simple steps you can take to stop people who are trying to hurt you.
Change Your Settings
Update Your Notifications Let’s start with the Account Settings. On the top right of each Facebook page there is a link called Settings. Click on that. Then click on the Notifications tab. Make sure that you are receiving an email every time someone posts to your wall, tags you in a post, tags you in a photo, tags you in your own photo, comments on your photos, comments on a photo of you, comments after you in a photo, comments on your photo albums, or comments after you in a photo album.
You also want to be notified if anyone replies to a discussion board post you made if you belong to any groups.
You also want to be notified if someone tags you in a note, comments on your notes, or comments after you in a note. Same for the links. You should also be notified if you are tagged in any videos or if anyone tags your videos. Also allow notifications of video comments about your videos or in videos in which you are featured.
Finally, you should be notified of any comments on a story on your Wall or if anyone comments after you on a Wall story.
Be sure to save your changes at the bottom of the page.
These are all areas where people can leave nasty comments or use as a way to harass other users. If the comment is made on your Wall, photos, videos, etc., you can simply delete and block the user (more on that in a minute.) If the post is made to someone else’s Wall, photos, videos, etc, you can report it. After each comment there is a link that says Report. Click it.
Change Your Privacy Settings
Go to the top right on the Facebook page and this time hover over Settings. A drop down menu appears. Go down to Privacy Settings and click on it.
We’ll start with your profile. Click on Profile Information. On this page, you will want to change all of your settings to Only Friends. Here, you can also change whether your friends can post to your Wall. If comments get particularly bad, you can uncheck this feature and no one else can post anything to your wall, even if they are on your Friends List.
Near the top on the left, click on Back to Privacy.
Click on Contact Information. There are two ways you can control this information. You can change all of these settings to Only Friends, with the exception of the Add me as a friend which you can change to Friends of Friends. Remember, you don’t have to add people as friends. You can ignore them. If you want even more privacy, you can choose the customize option and choose to make this information visible only to you.
The second way to keep this information private is to not put any of it on your profile in the first place. To edit this information, click on Profile in the upper left, then click on the Info tab. Here you can edit or remove any contact information you may have entered. You can also change who is allowed to see this information.
Back in the Privacy Settings, click on Search. Change the Facebook Search Results to Only Friends and uncheck the Public Search Results.
Go back to Privacy. Click on Block List. This is extremely useful if there are a few people who are causing you the most trouble. Simply enter their user name (their name as it appears on Facebook) and click Block. Or enter their email address and click Block. The people you put on this list will no longer be allowed to interact with you. Double check and go to your Friends List and remove these people as your friends. You have every right to do so.
Removing Content from Your Wall
If you have comments on your wall, you can delete them. On your Wall, move your mouse to the right side of the offending comment and click on Remove.
Report the Harassment
You will need to do this step before blocking a user and it will only work for people who are not on your Friends List. Go to the profile of the person who has been harassing you. Scroll all the way to the bottom of the page and in the left hand corner you will see the link Report/Block this Person. Click on it and fill out the form that appears. You can block this person at the same time. The report is kept confidential.
If the Harassment Continues
If you have changed all of your settings and blocked the people responsible, you can continue to be harassed or bashed on Facebook. If a friend notifies you that there is someone who is continuing to bash you or try to get others to harass you, ask your friend to report these people as outlined in the Report the Harassment section.
