Not necessarily by bots, but a lot of product-related articles - say, “What’s the best washing machine?” or “What’s the best hot wire cutter?” or anything like that - will have multiple near-identical articles across multiple websites with links for each product generating a kickback for the author. Whereas Reddit was just people talking.

Articles like that are probably starting to be written by AI for sure though. You could write an article on every type of product that way, and get kickbacks from all of them, all while depriving people of actual useful info. Woo, innovation!
