I’ve replaced all of my Reddit comments for the past year with AI generated nonsense. It seems to have stuck. I plan on going through all of my past comments but will spread it out over time so that it’s harder to restore.

IMO the key is making a post that writes gibberish but that is good enough to suck a user in to read it for a few seconds before they realize it is BS. That kills the user experience and poisons the site.
