Maybe it'll also mean turning off user generated content too, and only have admin made posts, the same as Digg did. They could hire the power-users to keep making the relevant posts.
People you don't have on contract are a liability
Shadowban all users. Respond to their comments and posts with AI generated responses only visible to the poster. Redditors famously don't want others to know their handle so they won't share it around. You could only tell from a signed out device reading something you commented in.
Flood the site with generated posts and 'engagement' that is all ad friendly. Turn the whole place into Weenie Hut Jr.
Do this pre IPO then bail forever.
There's a lot of reposted content too. I tried to farm r/poetry to feed my LLM, but the top stuff are the same reposted poems and edgy anti-poetry. Reddit could just repost the same thing again and again.
