It’s annoying, I see it a lot too. I think it’s mostly people second-guessing or regretting their own comments or posts. I’ve had great conversations with people, only to go back and find the whole thread was deleted. That has happened way more than I would have expected.

I don’t think it has anything to do with LLMs or slop (and I hate the slop), just people afraid of admitting they’re wrong or leaving an unpopular opinion out in the world after it’s been sufficiently argued away.
