Based on what I've read, I think I can safely rule out a con-

Among the intelligence people I follow (such as Rich Higgins, former NSC staffer), the consensus seems to be that Q is a psyop against POTUS, from either a foreign or domestic intelligence[1]). People can decide for themselves.
I can't point to any concrete "predictions" from Q other than Ted Cruz's campaign was also spied on. The only "prediction" with a date turned out totally false.
