These people stole, did nothing to tell any devs about the security hole and then tried to get away with it. Only when chadz got them they confessed and told anyone about this. I never saw anyone of them regret it in their essays ether. They should not be allowed back. BUT! IF they do then make them suffer for it.
They stole heirlooms right? So what about putting a level cap for all their characters at 30 and never letting them get any heirlooms again. No access to the market ether and no ability to use the skip to level 30 thing. Level cap at 30 for them and no market. Let them on strategus tough, or they will just buy new CD-keys. This is the pay off for their stealing and delaying strat.
