Then LLM bots got on and it turned into an email spam folder.

That predates LLMs, but I get your point.

But besides bots, there's also "low value" comments, the "who's listening in 2026" type comments. Undiscernable from a bot, adds no value, can be omitted and you wouldn't miss anything.

And the worst part is that LLMs can generate more interesting comments than a large chunk of online people can.
