We need to nominate a dude to the mod team for the EXPRESS purpose of banning this weirdo's alts. I'm grateful to u/DomitiusofMassilia for popping in every few days, but sadly that's not frequent enough. We need a daily reader who can just hit "ban" when he's browsing comments. It won't solve the problem but it'll alleviate it.
We could also freeze new account creation and open it for select periods, announced with pinned posts. Our growth would be disrupted of course, but it's not like that matters that much.
Because by sheer volume, he's shitting up the place and making the experience worse. He'll probably drive away a couple users, and we're a small community to begin with. A ban is well deserved.
Is there any real method of banning him?
Just downvote and move on? He doesn’t take a second of my time.
