Correct me if I am wrong, but isn't ShadowBot a bot itself?
So what if the other bot owners fight back and decide to start flagging your users, just like you do theirs?
All the users of ShadowBot are listed in the admin section, so it would not be very hard for someone to do. I think this is a terrible idea that jeopardises the safety of ShadowBots users.
Besides, how is ok for ShadowBot to upvote posts but not for other bots?
We do not ever flag anyone (or at least down vote them). We are simply generating lists and curating data that can be used by others to determine potential spam and abusive accounts. If you look into how email filters were created you can get an idea for how we are approaching this process. We are taking a monitor and see approach. Defense, not offense.
