I still can't tell if most instances of them are a) genuine, b) trolling stupid people into believing dumb shit, c) trolling smart people into believing they believe something stupid and enjoying the frustration as they fail to convince them otherwise, or d) conning true believers like that guy who just wanted to fund his private rocket launch did.

Like it started with group B, but it's impossible to tell group A and C/D apart, if they are really dedicated to the bit. Like those youtubers who did various expreiments that would show which way it was, got results consistent with ball earth, then dismissed those results as something being wrong with their experiment could be strong denial but also just sounds like trolling and if I had to bet, I'd probably bet on it being a troll (or someone knowing their video will get way more hits like that because it's a hilarious result that did get a lot of round earthers to watch to mock it).

Tldr, I think we might all be getting played, though none as much as the poor fools that really do believe and donate to "flat earth science".
