The only way, in my opinion, to stop bidbots is to create a negative stigma around them. Call the users thieves, because they are stealing from the reward pool. Call the owners scumbags, because they are enabling the thieves. Do this in every post. Even if it's just in the form of a banner. Most of us don't have the vested share to really do anything about it. But we all have a voice. And together we can mold this platform into a much better place.
