I think about this a lot.

I believe the reason for it is to harvest Meme Magic.

Money literally cannot buy Meme Magic. Billions of dollars are spent on advertising and media, and it almost always falls flat; people don't pay attention to advertising, and few people believe the MSM. I can't count the amount of clients who want something to 'go viral', but generating content that is share organically is like trying to catch lightning in a bottle.

The biggest meme generating platform in the world is /pol/, memes produced by /pol/ have the furthest reach of anywhere. Q posting on /pol/ allows the Q team to bypass the MSM and reach the people. It bypasses censorship and gets people to ask questions that they're forbidden from even asking. Suddenly three years later the Overton window has shifted further than the Mockingbird Media ever would have wanted it.

Most people who know about Q have never been on an imageboard; I've seen several people on here act like they're scared to even go.
