facebook.comは安全ですか？

Facebook is good about keeping content safe for work and hidden from the public, which is hard for a social networking website. Zynga, Inc., which runs most of its business through Facebook, attempts to make deals with people who play their games. These deals are extremely unsafe.

Photos or informations about you can be viewed by lot of people, even if you don't wish so. Nothing can be really deleted whereas the most of the members put informations/photos whithout really thinking.

Look at their terms of use agreement. They have the right to reformat, display, alter, and modify any data you submit. It means they can give it to third parties, even your government. Anything personal you submit (e-mail, movies, books you like, your number, address, favorite type of coffee etc...) is stored and kept as long as they want, and it can be given to advertisers and governments. It's violation of privacy.
