collapse of the old society

Who is the 'bad guys' is going to depend on who's paying for the service. This thing sounds like an atrocity waiting to be unleashed. I might have less issue with it just as a 'rally call' tool to bring attention to a post, but the provisioning of generated content for these users to post is just going to turn the whole concept sour.

We already have some idea what happens when AI starts feeding on their own output, those minor errors that nobody corrected end up being ingested and mutated/amplified further in a self defeating cycle of rot. Granted humans are pretty susceptible to the same behavior, but at least with us it's not done at machine speed.
