> I've also seen entire threads get "replayed". Bots will post highly upvoted comments from the last time a link was posted etc.

This is so surreal until you realize it is happening. You kinda know you have seen it before but not really since other comments are different.

Ye Reddit is syntethic nowadays. Some niche subs are OK with strict rules on content.

But the loose ones are too much karma farm and bots to bother.

It wouldn't suprise me of there are like 100 people doing most of the posting with alt accounts and semiautomated workflow. Both as commercial shills and political manipulation.
