I'm sorry for your bad FB experience! I really don't like it either. If I ever did a FB page again, I would make sure I kept tight reigns on it. I had a FB account set up FOR ME by someone without my permission (a "friend" that I worked for no less, not a "real friend"). I had problems with it from day one and pretty much have not even looked at it in forever because everytime I did, it froze my laptop. Whenever I would try to do anything really on it (from download apps to approve friends), it did it. Long story short, I have ignored that it was even still up until about a week ago when I logged in, but it wouldn't let me see my own friend's list (so I suspect the old "boss" might have still had access, I know so stupid on my part). I was able to successfully get a new password set, finally get access to the friend list, and deleted about 15 people that were not real friends, most were old coworkers that I have no contact with.
Anyway, I see so much potential for misuse of sites like that. It just doesn't appeal to me that much to be on them.
