I don’t even know what “QAnon” is!!!! Phooey, anyway!
It's similar to FR but there is no moderation. Anybody can post anything.
A team of anonymous posters that goes by "Q" occasional posts damning hints about the political class. Some (hints) pan out, some don't, but the overarching thrust is that the government is not honest with the people, and powerful people are not subject to law enforcement.
Another theme is that the press works for its master, and its master is not the public.
Another theme is that Trump is throwing sand in the gears.
Being an open board, the location of these posts also attracts persistent "naysayers" who cover the board with garbage.
The "theory of Q" that the press is advancing is incorrect.
