When I ran a WoW server years ago, I had tons of incidents with exploiters. But I watched them and learned what they did before I banned them as to fix the problem that lays before. Knowledge is a lot more powerful then the mighty hammer sometimes. Did me allow them to exploit to give me knowledge affect my server? It absolutely did, I was able to remove the mobs, fix loot tables for broken mobs, and so on.Jaycub wrote: if the original exploiter/duper is found to ban him.
Creating a new account is a dime in a dozen, but squashing a bug/exploit is priceless.
