There's a ton of LLM spam on platforms like Reddit and Twitter, and product review sites.
If anything it's just the same regular spam that gets deleted and ignored at the bottom of threads.
Easier content generation doesn't solve the reputation problem that social media demands in order to get attention. The whole LLM+spam thing is mostly exaggerated because people don't understand this fact. It merely creates a slightly harder problem for automatic text analysis engines...which was already one of the weaker forms of spam detection full of false positives and misses. Everything else is network and behaviour related, with human reporting as last resort.
There are articles written on LLM spam, such as this one: https://www.theverge.com/2023/4/25/23697218/ai-generated-spa.... Those are probably going to substantiate this problem better than I would.
Everyone who disagrees with the hivemind of a subreddit gets accused of being one of those things and any attempt to dispute the claim gets you banned. The internet of today sucks because people are so obsessed with those 3 things that they're the first conclusion people jump to on pseudoanonymous social media when they have no other response. They'll crawl through your controversial comments just to provide proof that you can't possibly be serious and you're being controversial to play an internet villain.
I'd love to know how you dispute the claim that "you're parroting Russian troll talking points so you must be a Russian troll" when it's actually the Russian trolls parroting the sentiments to seem like real people.
