Why wouldn't the media, government and/or intelligence agencies reveal Q's identity and expose the fraud? They have the resources to do this, nobody is truly anonymous on the internet.
It would also serve the purpose of demoralizing the entire movement at a crucial time and they could argue that it was necessary for national security purposes.
Unless...?
If Q were a larp it would mean Q is controlled opposition which would mean it was DS controlled and violent radicalization would be pushed.
Not one Q post calls for violence but the opposite.
If Q called for people to do anything remotely violent, even name calling (omg micro-aggressions!) it would be a sign.
That's what I think.
