Dave , 4 days ago I am convinced this is already happening. One example is the endless new accounts posting ibtimes links. There are also propoganda websites posted regularly by new accounts (especially sowing disinformation about Russia's war on Ukraine). Basically be wary of anything posted where it's their first post. Often they make accounts and don't use them for months so they look older. I also think astroturfing is happening but at lower rate than reddit. Like you, I have no idea how we can counter this at scale.
