I don't even know why people have to say where they got the game. If you pirated it, I don't care, there's no reason to say you did unless you think it makes you look cool or smart or something.
Posting information about pirated games is just asking for trouble, "free speech" or not. This is a game discussion forum anyway and not a piracy or 'where did you get the game' forum. It's unnecessary and can potentially cause problems to say you pirated something so why do it?
