Two reasons, both stupid.
1. It's the rules. You can't post a picture of a name AND say they are doing something improper. "Name and shame" is improper.
2. Only the "special team" can actually do anything about the bots. That requires filling out a form elsewhere. In game reports go to the GM's who cannot, in any way, do anything with, to, or about the bots, or they get fired. Nobody on the forums has any power over anything in game, so posting here is quite useless.

Yha, I said they were both stupid reasons. It's just how things are.
