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.
I don’t think we can compare this situation to Beehaw, since Beehaw disables downvotes and they also don’t follow people around on external instances to ban them. This is very much a different situation than Beehaw being Beehaw. It’s not exactly power-tripping but it’s bordering on the realm of Power tripping.
