Безопасен ли facebook.com?

Facebook is terrible with privacy, I deleted my photos about a year ago. To this day, they did not remove the picture "physically" on the server. In other words, I can still see my picture on facebook.com domain with a long tail URL. A company whose practice works this way on public URL, I don't know if they are really deleting anything or not. They might be backing up all the data and not showing it to us.

I used to trust facebook up until this last year they have been under fire at the US congress, and news media outlets and now by its users they have an unethical privacy policy were they make your private information publicly viewable, and sell the information they collect through there games and applications to marketing firms around the world DO not TRUST this website just read the new york times if you dont believe me

Facebook is failing on all levels; The default email settings are 'Full spam' - Even when you deactivate, they keep all your details, with no way of full deletion - There are known cases of children being 'groomed' on the site (one such child was murdered in the UK) - They never respond well to customer requests - Their 'privacy' settings change almost every month and usually leave personal details exposed by default!
