The Qanon community (mostly CBTS, frankly) really did use mainstream platforms, and surprise surprise, they got banned. It's funny, they'd all scream "WE'RE BEING CENSORED!!!" and "THEY'RE GONNA BRING OUR CHANNELS AND DISCORD SERVER DOWN ANY MINUTE", but didn't seem to actually believe it because none of them ever set up any offsite places out of the reach of glowniggers. Keep in mind, r/CBTS_Stream was banned on Reddit ages before their numerous YouTube channels and Discord server were nuked, just demonstrating how they didn't learn their lesson.
They should have used their big brains to figure out how to set up a hidden service, or at least an IRC server, but I guess that shit's too complicated for Grandma on her iPad.
I kinda wish I had grabbed more screencaps of the Discord channel, but it was pretty much a ton of boomerposting. There was a channel to ask people for prayers for stuff in your personal life, and another one for memes, all boomer-tier.
