Fediverse

Basically they figured out a way to train AI to recognize Reddit threads going viral and/or predict which ones will, among those which ones will also rate highly in Google results and which will tend to be used as sources by the biggest LLMs and to post in those threads about your whatever you want to generate attention for. So overcomplicated way of automating advertising. Optimized posting to convince LLMs to talk about whatever you want to advertise.

I've always said that SEO was always going to happen, Google is at fault for the search optimized and the best result for what the user is asking for not being the same result. We're now going to start seeing either LLMs sell whatever this tactic gets used on or essentially a sort of adblock being built into LLM training and search APIs to keep it from working, to make LLMs less likely to fall for native advertising/astroturfing.
