Hey don't feel bad! Anyone with this pattern of behavior is very clearly toxic. The action that they do with blackmailing or blaming their poor mental health on you for some reason, is very toxic and abusive.
Look, they say they did stuff for the community. Sure, but the way they did it seems...transactional. They are saying they did all those things, and because of it, they want something in return(to get unbanned, their ideas implemented, to talk to you, etc). That is not doing something because of the goodness in your heart.
Keep on focusing on the game! Once this game is complete all of this doesn't matter. We are here for futa porn lol, nothing else. If anyone else wants more than that, then that's on them
