1) I can't block everybody. I can block one guy but then some other idiot will message me. 2) It would actually be funny to see how people react when they buy an exotic and then Xur sells it that week. That said, people would buy probably pay good money for Hawkmoon on PS and probably Thorn (especially people who suck at PvP). 3) Except it ruins the game. 4) Perhaps, but some of them are still people I enjoy playing with. When I said "friends" I meant PSN friends, not real friends. Either way, very little good come from allowing trading and it can result in a lot of harm.
