Are there online stalkers on Facebook?

There aren't. Because your profile information can be hidden except to your friends.

I would have to disagree with this answer... there are always opportunities to be stalked, i was stalked by one of my ex girlfriends, she made a profile with a person name i knew, and i added her, and then she was able to look at my profile and harass my current girlfriend, so pretty much, if you dont add people you dont know, then you cant be stalked!
