Or more precisely: Why is there a majority of people who upvote those theories but moderators can identify them as what they are and remove them? What has happened to moderators that they can handle the 'theories' that hasn't happened to regular forum members?
Whatever that is, can't this be handed out to new members before they are allowed to vote?
Part of that is very much ensuring that the front page is not wall to wall conspiracy theories, and members don't have every thread inundated with the same junk.
From the evidence of outsourced moderation, they started being influenced by conspiracy theories and suffering from PTSD
There is a serious logical hazard in believing that any of this is asymmetrical.
Take the recent US election for example. Very effortless to claim fraud and stolen election; just a couple of tweets in fact. Debunking them rather more difficult. Then there are the more specific claims, such as:
- China and Venezuela worked together to do this - Voting machines flipped votes - There were vote dumps at midnight - Dead people voted for Biden
All very easy claims to make, all rather more difficult to debunk sufficiently. Then, when one is debunked, another one easily pops up. Don't get me wrong, I think it's well worth the effort and we should fight disinformation, but effort it does take.
