All free-form adverts are supposed to show some kind of sponsored label, though that doesn't appear to be the case on the three posts included in this story. While Leica's shows it, neither Philadelphia post includes a tag indicating it's sponsored content. We understand that's because the Philadelphia posts are no longer boosted by ad spending, so are back to just being normal user posts.
Ad stays up in perpetuity, tag has a shelf life, after which it looks like a normal post. Can you sponsor a post for an hour like it's a seedy motel room?
Also: As these are regular posts with brief decoration, I'd assume uBO might have trouble filtering them out.
Sounds like a great way for Reddit to force anyone trying to train an AI to pay for an ad-free dataset: buy the clean one, or scrape an ad ridden one. You wouldn't want risking your corporate AI to spew propaganda about your competitors, would you?
I don't know what to do to get good search results anymore if this happens. Using site:reddit.com has been the only way recently to find opinions from actual people regarding some product I'm considering. Maybe I'll just stop buying things and go live in a cave. Can't trust any information online anymore.
