Facebook owns everything you post, they own your identity but you don't own it. Everyone can steal your stuff on faceboook but they can decide in one day not to let you access it anymore. I am very surprised that it is ranking number one as i don't see a lot of positive comments here. I believe that WOT was created by Facebook, so that Facebook can seem more legitimate with their bad practice.
Definitely NOT an ethical website. Lots of porn, spam, phising, irritating games, you name it!
Watch what you click here. The official Facebook links are okay, but the things users post isn't.
Malware often takes over users' accounts and makes fake posts that lead to a malicious site or include malicious code.
