@jasonkoebler's https://www.404media.co/ai-is-poisoning-reddit-to-promote-products-and-game-google-with-parasite-seo backs up my assertions about the death of social media in https://boehs.org/node/llms-destroying-internet
Though, he states that reddit won't become an AI hellscape. I disagree. It already is one.
Where do the "high karma" accounts come from? They come from huge subreddits where the bots have begun posting marginally related content that people blindly upvote because "cute animal" or whatever (+voting rings). The quality control is gone. The frontpage is governed by bots.
