@pfunk If I had that power I would. But I don't so I can't.
Best I can do is try to encourage others to act responsibly.
@anyx already said he wouldn't implement leashcodes on @cheetah and like I told him, no one expects the police to leash their K9 when they attack. No one expects other police bots like cheetah to obey leashcodes either. Also not all bots are chatterbots, actually most bots aren't chatter bots.
One thing you can do though, is to explicitly ask the bot owners to stay out of your threads by using #STEEMBOTSTAY I know 7 bot owners now who have agreed to respect that. More will follow.
