There's a bunch of LLMs. Not actually that difficult to find.

There's even some pretty obviously shady ones doing stuff like purposefully evading LLM detection systems.
It also does not take that much of a search online to find people trying to buy upvotes, comments, accounts. A lot get banned, yet people are still obviously trying.
Generally agree with you. Lot of sites over the years that have eventually been turned into wastelands. Predictabot LLM SEO spew that eventually rendered interacting there meaningless. The auto-comment, auto-review stuff has been around longer than the LLM idea, it just wasn't quite so accessible. Now its like every teenager has been handed bioweapons.
Unfortunately, (opinion) most of the mainline World Wide Web has been reduced to content that's difficult to parse from Stock Market summary bots, and most of the old vibrant forums have slowly been obliterated, so there's not that many places to go to.
Huge portion of the World Wide Web that just goes from site to site ruining the experience until there's nothing left, and no reason to participate, or even glance. Their calculations wasted turning each "platform" into a pile of vomit no-one wants to interact with.
