I think the forum is moderated well: personal attacks aren't tolerated so the discussions are generally pretty cordial, but still allowed to get a bit heated and frustrated some times which is understandable for something so polar: both sides think the other side is completely ridiculous. The "tone" set is remarkably good, compared to how quickly you tube comments descend in to completely ridiculous ranting from both sides. Topics are "usually" kept on point.
Of course the idea of a global conspiracy from the space industry is one of the most ridiculous concepts required for flat earth belief... But if you WERE a member of such a conspiracy, and you wanted to "whistle blow", you wouldn't do it here: you'd go straight to 60 minutes for millions of dollars. Hence why the conspiracy theory is so ridiculous: there's little motivation for someone to keep it a secret (i.e. if the world was flat, who would give a crap? if it's flat, it's flat. I mean it ISN'T, quite clearly, but who would care if it was? Certainly not scientists, they would WELCOME any opportunity to have a "greater understanding" of the world. A flat earth pretty much proves the existence of god (i mean, how else would something so ridiculous be possible?) so that's an explosive revelation, but again, why would that motivate people NOT to tell anyone?? A religious person would have every reason to reveal that! So 1) huge financial motivation 2) huge religious motivation, not to mention the prestige of such a leak 3) huge fame motivation, 4) huge motivation just based on the fact that people don't "like" to keep secrets.
Interesting article I found on the manhatten project, probably one of the biggest things kept secret by thousands of defence force and private contractors (apparently about 130,000?). Still, there were 1500 reported investigations in to leaks. That project ran for what, 4 years? Imagine how many leaks in 70 years of space industry...
https://io9.gizmodo.com/secrets-of-the-manhattan-project-were-leaked-a-staggeri-1626524763?IR=TThe HUGE advantage the manhatten project had, was that people were at war: who in their right mind would knowingly leak something to someone who might literally destroy them, their families, their way of life... If flat earth were revealed tomorrow, the only thing people would care about is "why the hell did you keep that a secret?" it doesn't change peoples lives one bit. If a bunch of people then believed in god because of that revelation: big whoop. The only way to keep a secret with NO motivation to keep, and A LOT of motivation to leak, is with a hell of a lot of money and a hell of a lot of violence. Ironically that activity would be the thing that gets peoples attention and unravels the leak.
