1. Only accept friends you know
In order to prevent harassment from strangers, only accept friend requests from people you know and 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. Only confirmed friends can post to your Walls or contact you via Facebook Chat, so if you’re worried that someone will make inappropriate posts or send offensive messages, you should ignore that person’s request.
2. Stop abusive behaviour
A block prevents someone from viewing your profile. If you receive inappropriate or abusive communication, you can block the person by listing his or her name in the “Blocking People” box at the bottom of the privacy page. In addition to blocking, if you receive abusive messages on your wall or via Facebook chat, you can remove the offender from your friend list.
3. Report trouble directly to Facebook
5. Don’t react to bullies – block, report or delete them
Rather than responding to a bully directly 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 “Blocking” or “Reporting” 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. Because only confirmed friends can post to a Wall or send a message through Chat, users who don’t like the posts and Chat messages they’re receiving should consider removing the people responsible from their friends list.
