Facebook granted unauthorized access to Y! account?
There was a chat between me and an unknown person on Y! chat long time ago. It was just few lines although. Today when I logged on to FB, here it shows me that person's name under "People You May Know". FB has been continuously asking me to provide access to my email account saying "Friend Finder" or something like that. But I've never accepted it because I don't want to connect with my Y! contacts on FB. I suspect Facebook have unauthorizedly accessed my contacts in my Y! account. What is going on?
I'm 100% sure we don't have friends in common. Maybe its just coincident?
