ok, I have a facebook account that I almost never use. when I open Rotten Tomatoes.com it automatically identifies me using my facebook picture and name. the say they work together with facebook. the thing is I never told facebook that I use rottentomatores.com nor did I tell rottentomatoes about me or my facebook account. it seems that rottentomatoes accesses some cookie and identifies me. not a big deal in principle but it sucks. how is that legal? or did I at some point make this connection by mistake? Can anybody explain this and point me to a method to block websites from finding out my facebook ID?
