Some Redditors actually have some experience with this, because some subreddits award Community Points which are really crypto tokens based on karma. I earned enough shitposting last year that I had to figure out how to properly declare it on my taxes.

While it increased traffic, most of the increased traffic were low effort posts and the same old jokes farmed for Karma. I think there were even more bots there, too. Real discussion sometimes got upvoted, but a well-timed Elon Musk joke could earn $20 or so

If something similar is implemented site-wide, this (in conjunction with the API changes that hinder moderation) will no doubt result in an influx of bots mining memes for cash.

Now that I quit Reddit, I need to figure out how to sell those now.
