Wait, what’s that? They were doing it to exploit the game and make in-game money? Well, it doesn’t really matter why they were doing it, because they’ve been summarily banned as part of an ongoing investigation. And it’s an investigation that ends in a place where they’re unlikely to get the bans overturned on appeal.
As usually happens, the community staff is not naming and shaming; it’s enough to know that the bots are gone and likely won’t be back. Or, at the very least, will have to buy the game again, which is a blatant cash grab just because the botters cheated egregiously. So, hopefully they’re gone for good.
