I'm pretty sure the majority of content on reddit now is from bots as well (I used to moderate a medium sized subreddit pre-LLM, and the amount of automated posting was concerning even then).

There's a ton of bots here as well (especially if you show dead in /newest), but at least people are able to spot it and call it out here, (human) redditors seem completely oblivious.

Yeah, and even more concerning is that there's a thriving market in "high karma" reddit accounts. These are bought and sold for marketing/astroturfing, often run by bots. So a human today can be a bot tomorrow. And the way Reddit works, which is not really the case here, is that high-karma accounts are privileged in terms of post placement and de facto status.
