I've come to the conclusion that pirates will be the greatest weapon against AI spam content, especially when it comes to books, movies and music. Commercial interests like Amazon or other sellers will never filter out AI content if they can make money from it. Likewise social media and other ad sellers will never filter out AI content if it can grab attention for ads. The only people who have no motivation to let AI content through are pirates, because they share content at a cost and at a risk.
