Does not respect privacy of the users.
Privacy settings are not securised at all by default and the average user does not have the knowledge on how to set them properly.
Not much of a learning curve. Noobs can pick up the basics of facebook use easily. You're often not as private as you think you are and children are more in danger of being bullied than they are of being contacted by strange people. it's easy enough to deny people you dont know who request you as a friend.
Overall this site is safe and enjoyable for most safety conscious adults. However I had to give facebook a poor child safety rating due to the sexual viruses that are often released on it as well as the potential for contact from complete strangers, possibly with sexual or harmful intent.
I love facebook for chatting a playing the games. I am 50 yrs old and sitting around for a few months with Rheumatoid Arthritis and just had a "REVERSE ROTATOR CUFF REPLACEMENT". So playing the games ie: Zoo World, Farmville, Citylife and all those are my kind of fun. Sad - True - but SO VERY FUNNY!!!!
As of now I can't access Zoo World. I can access everything else like I do from home but that. So if anyone can help me PLZ email me or whatever is easy, fast, and not an inconvenience to you. PLZ PLZ HELP
