So role-playing a Smuggler can get you banned?!?!

So me and my cousin are playing SWG. We are both smugglers, you know, that dity, underworld, theiving class. Well we made friends with some uber guys in-game and one of them gave my cousin admin access to all his shit. We were talking about how the guild was bullshit and how these guys were jsut a bunch of pve noobs, so we said hell, lets take this shit and go off. So for about 2 days we had all this guys shit, like 3,000,000 credits and laods of loot. One day my cousin calls me and says the gm froze him when he logged on. I logged on and was frozen as well. So I asked the gm what was the problem, and he said he was taking all the shit we had. i responded with, "Hey, I'm a fucking smuggler, i'm just role-playing my charachter." He then responded with, "Hey, I'm a GM, your banned, I'm just role-playing my job." So that was the end of that account :(
