I mean, it could come from archaeologists and biologists just embracing it. Bigfoot hunters may be jamokes but to your point a lot of them are the type of crazy that goes deep into unexplored woods for weeks at a time.

If we just had an institution that was like “haha, yeah, wild, I hope you find Bigfoot. By the way, while you’re out there, if you could just keep an eye out for these anomalies and send us their location if you find them that would be swell. We won’t report it if it’s trespassing or whatever.” They could do a lot of good.

Big foot is one thing, it’s more of a cultural phenomenon. Flat earthers fundamentally believe that all authorities are lying to them so it would be a lot harder to get them to play along.
