>I would suspect there's good money in offering a service to detect AI content on all of these forums and reject it

This sounds like the cheater/anti-cheat arms race in online multiplayer games. Cheat developers create something, the anti-cheat teams create a method to detect and reject the exploit, a new cheat is developed, and the cycle continues. But this is much lower stakes than AI trying to vacuum up all of human expression, or trick real humans into wasting their time talking to computers.
