Forces you to type in alot of personal info. It makes you type in your full name as well which becomes your display name. they show your email, phone number, and all info you put to the public, I'm surprised they didn't ask for a Social Security number to join the way the site is.
Theres a huge adult side to facebook where girls and guys swap adult pics so not really child safe. Regarding privacy its pretty awfull, sure you can create private photo albums but they can still be seen if someones commented on those photos. Theres also the fact that your friends numbers are stored on your phonebook as soon as they add their number to their profile
Site is full of spam and not child friendly ads. The site also seems to be untrustworthy for privacy due to many changes in their Terms of Service. The site is also discriminatory towards certain groups of people.
social networks generally should be treated with suspicion. You can never be sure, who is accessing the (personal) information you post there. Particularly analysing a users behaviour and network is used to generate tailored advertisements or can be used by third parties for some marketing purposes. Not to mention, that drinking pics may raise the suspicion of your boss...
Facebook OWNS everything you upload ... personal information, pictures, and even videos. They all get stored and get used by facebook as the want ... and do it legally because it's part of the terms and conditions that everyone agrees to when signing up.
Even with the highest security settings active, anyone can still view everything you post with a simple link exploit. There are even 4-5 different viruses spreading through facebook.
Extreme caution should be used when using this sorry excuse for a social network.
