Maybe it's to make an example of them? Let the zombie subreddits stand as an example of "This is what happens when you cross the admins."

The quality started out shitty on some subs. Fuck spez, but he's not completely wrong about the mods. Some are people who never have and never will have more power in their lives and it goes right to their brain. Where he's completely wrong is blaming this situation on the mods when they are just the group of users who can frustrate him the most. I bet he thought he could throw the mods under the bus because they were already generally unpopular (though some subs were bad and others were fine) before all of this.

Something nice about the fediverse is that instances can be dedicated to mod evaluation. They don't have to honour deletion requests; they could specifically highlight them instead to see what kind of posts specific mods are suppressing. Hopefully that can be used to check their power and reduce how much of it goes to their heads.

I'd love to volunteer as a scab. Problem is, what's stopping me from running any given subreddit in a way that destroys the community further, like arbitrarily removing posts or banning users while simultaneously allowing clear spam/bots/scams to persist?
