You can be sure that there is a team in charge and bots are being banned non-stop, keep in mind that the bots continue to be created in a massive way, so despite the measures you mention, it is necessary to find a more efficient solution to such a deep problem.
We appreciate the help with the reports that all players make through the game since through them we can locate and ban the bots, we promise that we are working on it and we will find a more efficient way to deal with them.
long story short: I once was owner of private server for an MMO.
I had bot problem too, and I managed to make easy fix, with zero cost.
Create a script, that is triggered by bot actions, and use it to simply teleport that character to a zone under textures, where you can not use songs or unstuck, and no access to mail box and storage.
The bots will be trapped inside a game, and they will just leave the game.
If the presence of game master would be visible on server. That might intimidate the boters and gold sellers too. And people banned would be globally announced. That would help to improve AGS face too. And it would boost player morale.
