Most scammers have obvious names, I have recived messages from people with names like, I will steal your games, and Upstanding Gentleman. If your really that worried just check back as many pages as it takes to see just how many groups have started and how many times people have complained about scammers.
I have never seen a Host scam anyone, most scams involve people trying to get the account info before they send the info, or taking more than one slot once they paid for an account.
Also make sure the host lets everyone activate the account on there PS3 before the game is bought that will avoid any other group members scamming you by taking extra slots and now you only have to trust the host.
