I agree, except there are a lot of fucking weirdos who care way too much about random stuff. I can totally see a random 4channer running a bot to smear a TV show they don’t like or something.

Serious answer: you don’t.

HOWEVER, it doesn’t really matter. The world is a big place, and you can find a decent size group who will expound any shitty opinion when given the opportunity. You already couldn’t blindly trust the information or opinions you found online, so whether it comes from a LLM, a troll farm, or just an idiot doesn’t really matter too much.
