you're the mod of a moderately successful game. you recently hired some helper mods to take some of the work off your shoulders. so far they have been helpful and good mods, but you have noticed some of your players becoming less active and pulling back from the game.

but then one of your players comes to you with evidence that one of your helper mods has been toxic and wanky in the past. they have clear screenshots of this evidence, which happened to them and is known to other players (but hasn't been brought to you before). they say they have opted out of the helper mods characters and have been trying to avoid them but this is becoming more difficult as the helper mods become more involved with running the game. they are worried that this helper mod will not be able to act without bias if they ever have a problem with the game and ask for you to mediate. they say that they are not the only player with this concern and it explains why some of your playerbase seems unhappy.

what do you do?
