This guy is clearly snooping the downvoters as an instance admin and retaliating against them. Wouldn’t even have noticed if I didn’t stumble onto the modlog in Voyager by accident.
I might be of course wrong in my assumption. But I don’t remember ever interacting with anyone from that instance, I’m not subscribed to those communities and the dates correlate.
PTB, but also confined to their personal instance, so nothing of value was lost. Let them power trip in their little sandbox, it doesn’t affect the rest of the world.
