Yeah, you may be right, but if the banned member was re-instated because someone had the heart to "buy" (really donate) him a last chance ticket back in, than maybe the banned member would appreciate the fact that he was given that chance, and may behave better. I mean come on, we aren't dealing with felons here. Some people loose their cool, and may go off track for a bit, but i'm sure that after a permaban they probably regret it and 99% of the time I dont think it's out of real malice. Again, i'm not saying the banned would be able to buy their own second chance back in, another anonymous member would have to donate their own money to buy back the banned member's membership, and also it would be a last chance. You never know.
On the plus side, it would be a good way for KLOV to have another avenue for funding.
