They are probably linking each of these botters/teleporters to their mules and patsies and will mass ban them. Problem is the web of RMT is large and you will never eliminate all of them, but you can hit them where it hurts by tracking each character to linked accounts. It will happen. I remember their first huge ban hammer wave in FFXI. If you go in and ban individually, it gets harder to trace where the gil is being distributed. When you break one teleporter it only takes out that account and then you have to research the account to see what it has done. Whereas you can track it and monitor its behavior as it interacts with more of its 'friends' dragging more down in the process. Think of it like it like NARCS. They aren't going to arrest the one lowbie drug dealer. They are trying to get deeper to find the source.
