This is exactly what happened with the early waves of mastodon migration; a whole load of instances suddenly had to up their game, there was defederation all over, and tooling had to improve to handle mod needs in larger communities. We’ll get there, it’ll stabilise. In the meantime, fund your server and thank your mods :)
Thing is, this isn’t AI causing the problem. It’s humans using it in incredibly dumb irresponsible ways. Once again, it’ll be us that do ourselves in. We really need to mature as a species before we can handle this stuff.
