I don’t recall saying anything about even attempting to change his behaviour, anyone with half a brain knows that’s a lost cause. The point is being a thorn in his side. He clearly cares or he wouldn’t invest the time and money into these games.
This goes against the TOS for both games. If you play either, I highly recommend flooding them with reports on that. It would be great to see him banned. He’ll probably just set up a new account and start again, but it’ll cost him and you know he’ll keep cheating so you can just rinse and repeat.
I’ve been asking people this a lot lately just to be sure there’s no fascists in my orbit. Thankfully everyone has answered Nazis so far.
