As I pointed out in 'Markets and Retainers' unless someone important at SE logs in to the NA servers and tries to sell anything on the market, they will never see it as the issue it is.

banning the teleporting ones in starter cities and the RMT barkers is going after the low hanging fruit. ban 20,000 of then, I dont care, but SE needs to raise the bar and go after the long term crafting and market bots. If they are serious about cheating, this is something they need to put more resources into. and if they REALLY need tips on how to find them, I am certain I and many other crafters can help them figure out who is doing what.
