What angle are you approaching it from?
I think LLM detection is gonna be tough, I think a verification route and cutting bots off from the source is going to be ideal but not sure how to tackle that while respecting privacy.
I did have an idea of a app using nearby devices and after flagging 7 unique devices it's tagged as verified, interesting but not sure it'll work in rural areas.

I definitely agree but I think that case would still get caught in the steam AI usage badge?
