SE, bots don't even try to hide anymore, they long ago stopped being subtle. Is it really too much to ask that you cull them a bit when they're so very obvious? Does it really need more than one GM to take a look at popular bot locations once per day and get rid of the very obvious cases?

No pay to play game should have such a rampant and obvious botting problem, and it seems to be still getting worse rather than better.
