You're definitely right that there are a lot of really cool people out there. I had a similar experience joining an EAA chapter to discover that a whole bunch of them had worked on Hubble.
That said, the FCC in my experience has been pretty lax about policing the amateur bands. You can go to any online SDR and tune around to find obnoxious, toxic, and illegal behavior within minutes. I've also found that if you're lucky enough to find someone under 50 on the airwaves, there's a >25% chance they're a crazy prepper.

Ah, so 4chan for old people.
Bad actors? There are a handful, but FCC has taken enforcement action against several. https://www.fcc.gov/general/amateur-radio-service-enforcemen...
Weak signal modes have been around for a while. And voice is a different part of the spectrum.
