The biggest problem is they aren't breaking the ToS by having level 50 classes, garbage names etc. Nothing can be done until they breach the ToS and you would need a huge fleet of GMs to monitor everything. Instances are the biggest issue since there can be several hundred of them minimum at any given time. You want SE to hire 200-300 GMs just to police the instance servers? It still wouldn't speed up the bans (which are done in the 100s each week if you read the Lodestone) because the GMs just feed all the info to another group who investigate and slap bans. The worst an in game GM can do is Gaol you and temp ban.
