I beg to disagree.

The reason all these delusional posts getting even upvoted to begin with is due to many like-minded people are gathered together in the same sub. As an example, reddit's r/democrats and r/republicans. One is clearly more sane than another, yet try to say something in a wrong sub - get downvoted to oblivion. But if you spill your delusional shit in a r/republicans - upvotes galore and comments of praise.

Facebook groups are the same shit. And so is Lemmy. One thing in hexbear that is allowed could/will be the reason you got a ban in .world. Up/Downvotes cant fix that.

tl;dr Village idiots can join together to accumulate their own conspiracies in a big ass circlejerk, and social media has no power to stop it.

Reddit has downvotes. That hasn't saved it from misinformation, trolls, and radicalization.
