Well they are looking into a new way to deal with the spam which we don't know the details of yet. But yep, it's as bad as ever on my world at the moment. The thing that actually bothers me personally more than chat spam is just seeing the clone bot characters around, in packs, sometimes even clipping through objects which normal players can't pass through. It hurts my immersion and annoys the heck out of me. A huge improvement to the game, for me, would be being able to prevent the display of certain character by adding them to blacklist, so not only can I not hear them but I also can't see them and just forget the problem is even there. It would fix my main problem with the game, so I can enjoy certain areas again without seeing notorious bots that work there for hours without being banned.
