Depending on what key words you use Facebook can cross post your comments into Muslim Brotherhood for example.

Watch the video to see exactly how typing in the wrong specific keywords will get your post cross posted to places on Facebook you probably had no idea they were going. The above example, "Muslim Brotherhood" if you just happened to say something about them in a post be it good or bad, your post will then be cross posted to the Muslim Brotherhood page. Be careful what words you use when making long comments or posts and take the time to see just where your posts may be ending up.
