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.
We can be more organized, to clearly present to Dom that new mods is what the community wants.
We should gather the nominations, then make a second topic asking people to vote on them by placing a comment (from a known, non-handshake account). "No new mods" should also be an option.
Then we should make a new topic with the results. Sort of like the KIA vote that was ignored, and was the start of KIA2.
And if the results of the vote gets ignored, we move.
