The best solution for dealing with AI content slop flooding your eyeballs is to hang out in places small enough to be a community -- like a local area mesh network.
AI slop thrives in anonymity. In a community that's developed its own established norms and people who know each other, AI content trying to be passed off as genuine stands out like a sore thumb and is easily eradicated before it gets a chance to take root.
It doesn't have to be invite-only, per se, but it needs to have its own flavor that newcomers can adapt to, and AI slop doesn't.
You can still find the essence of community on the traditional internet in places like invite-only discords, smaller mastodon instances, traditional forums, and spaces similar to Lobsters and Tildes.
...and not on Hacker News. Too many pseudo-anonymous jerks, too many throwaways, too much faith placed in gamified moderation tools.
