I don't really know of one on voat, but I do know that /r/conspiracy has more of that sort of stuff. In many cases they are a little too paranoid (ex: chemtrails, which as an aerospace student, I can tell you is garbage), but you'll certainly be able to discuss the illuminati/satanic stuff there, until/unless they get banned too, in which case they'll move over to voat. Personally I find the satanic end quite fascinating and frightening in all this, because we have so much evidence for it (at least with respect to Clinton campaign/Hollywood) and god only knows if the "will of Moloch" could start WW3 (bullet dodged there). Personally been meaning to look more into the Rothschild stuff after America cleans house over the pedo stuff, But I like seeing that people are connecting the dots all over the place, and I feel confident Trump and the tide of populism coming with him will play a major role in bringing the hammer down on all of this. Wish I could be more helpful but I'm not much of a social media user.
