I think this is actually a reddit, and all other similar platforms, problem. The issue is that there's good content, funny memes, insightful essays, whatever, that was submitted in the past. Some of it is no longer relevant and some of it your audience has already seen and would be bored by - but lots of it would be valuable to resurface now.
Because reddit focuses mainly on what's happening recently the good content of the past that might be relevant to a user today is buried. Reposters play a valuable role in resurfacing content. I think a better paradigm, though one I can't really imagine that well, would remove the need for reposters by automatically showing the content they would repost. Maybe a recommendation algorithm?
No, the issue is that pretend internet points always end up having real value, because human brains are lazy and rate in-group signalling really high and therefore trust ads that come from "big people" more. That's like the whole thing behind the influencer advertising economy.
Reddit didn't get rid of r/hailcorporate on accident. There are literal industries that exist to make fake accounts, karma farm, and sell use of those accounts to post basically sponsored messages that maybe even reddit itself doesn't know are sponsored. Think of how many people say "I search reddit for product recommendations" and know that companies have been pushing on that button for years and years. Whether reddit is honestly trying to prevent this kind of stuff doesn't actually matter, because as long as real moderation costs money and breaking that moderation makes money, the advantage is towards those who break it. FFS, reddit still has most popular subreddits modded by one account and their sockpuppets.
It no longer shows up on the /all tab for most users. I imagine that is due to some rule fiddling they did, similar to how one of the donald trump subreddits kept gaming the system to be most of the me page so they changed the rules.
