I mean, yes and no. The default Reddit experience is absolutely overrun by fake content. Or, there are tens of thousands of real people who have nothing else to do in their life but to go to /r/news or other "front page" subreddits and post the same political talking points multiple times a day, whether the story warrants it or not. Frankly, the AI / paid-shill explanation is greatly preferable in my book.
The non-default experience is a mixed bag. Specialized communities are usually moderated pretty strictly, including rules against outgoing links, product reviews, etc. That said, you definitely see product placement disguised as questions / off-the-cuff recommendations where some previously-unheard-of Chinese brand is all of sudden mentioned every day.
HN has its problems, mostly in the form of people pretending to be experts and saying unhinged nonsense, but it's far less commercialized. If you want your brand to be on the front page, you sort of need to make an effort to write at least a mildly interesting blog post. Now, AI is changing that dynamic a bit because we now get daily front-page stories that are AI-generated... but it's happening more slowly than elsewhere.
