What kind of game is this?

Game: Priston Tale

ok.... ive seen some stupid requests for games, but this one beats all. first of all, in order to register you need either your drivers licence, passport or SSN. WHAT KIND OF GAME REQIRES A SOCIAL SECURITY NUMBER? Second, i tried to email them and ask why they need it, and it says in order to submit a question i need to be a member. that is a load of bull___t! something is up with this game. BE WARNED..... THIS GAME MAY BE A SCAM!
