Like others have said, a heaven for data miner's and thieves. I regret using Facebook and I do not recommend using it. There are better ways of keeping in touch without compromising your safety and privacy.
The social network - facebook - is not really a bad idea. But it seems that the privacy statements of the site are really bad for the users. And currently it seems more like that the current states getting more and more worse ...
if you put lots of data in it. can be very dangerous.
they put bugs inside the site and get all of your data.
no good privacy. this site doesn't ever delete you data from its servers.
Сайт нарушает международные права человека,
в первую очередь право на общение ,
например я отправляю приглошение добавить меня в друзья а меня за это блокируют и ещё пишут что я занимаюсь преследованием человека если он нехочет пусть недобавляет меня в друзья , зачем тогда этот сайт создали если на нем общятся нельзя для рассылки рекламы и спама?
someone had tried to hack my facebook, however facebook blocked them, and wouldn't let me in until i verified that it is my account. even told me the general location of the hacker. very safe, and useful feature.
