There's a specific type of person that makes quick, unilateral decisions that effect entire communities, with out allowing time for community members or other admins to participate in a discussion.
They're called hoa presidents, and I think I can speak for everyone here; we do not want this community ran like a shitty hoa.
Give the mods time to decide how they want to deal with the artist's we don't want shared here. I don't want the moderators to curate it, nor do I think they should have the added workload of digging through an artist's history to verify they are an issue - which they have to do thoroughly because of how easy it is to edit a comic to be something its not.
I still think the easiest is to just have everyone put the artist name in the title. If the singular post isn't a problem, it can stay. If people want to block the entire artist, they can make a filter. Perhaps a bot could also be made to pick up on the artist's name and put an informative "BTW, this guy stinks" in the comments. If a user is repeatedly posting hateful content, then they should get banned.
Well that script was ran on enough other computers, so the magic algorithm decided if everyone else ran it, it must be fine.
