People are pretty hostile towards AI-generated content, so any platform wanting to remain relevant is going to have to take measures to keep out AI-generated content. If you allow it in, it'll quickly become 99% of your overall content and all the human consumers will leave.

As a side effect I'm seeing a lot of human-generated content getting labeled as AI-generated because it looks AI-generated. Sure, a lot of blogspam is going to be replaced by AI slop, but even human-written blogspam isn't going to survive the shift, simply because its quality is so poor that it is essentially indistinguishable from AI slop.

Right now we're in an in-between phase. Most people are still using low-quality aggregators like Google. This will inevitably have to change. Either Google & friends somehow get their shit together (I doubt it), or we're going to see a shift towards known-good curated content like 1990s webrings. I wouldn't be surprised to see a vetted-human Web Of Trust, but for content.
