The problem with Reddit is different. Poor quality human moderation is the problem there. Basically who has 10 hours a day to read Reddit? Answer, terminally online bubble people who have no business moderating other's posts. Maybe if the LLM could completely bypass the moderators then it could work though.

When I tried Reddit a while back, that problem showed up even with no moderation action being taken. I guess cause an obsessed person will use the site like 1000x more than a regular person, they end up being the "majority." The voting system also encourages bad behavior.
