All of them.
Let me tell you a funny story.
Once upon a time, someone invented a really awesome drug. It basically allows you to do multiple things, all the time, without even having to consciously work at it. It just hurts a little, and it's hard to get a hookup, but once you're in, you're in. Only way for the trip to end is death.
Somehow, everyone on the drug finds each other, and is able to coordinate without anyone else realizing. Even when they're doing "Multiple" things (hah! pun!) it only looks like they're doing one thing! They team up, and basically take over everything. The drug is so awesome, they give it to everyone who works for them, and since they dominate, it ends up with nearly everyone being on the drug. Eventually, it gets to the point the only way to get some jobs is to be on the drug. The elites give it to their children, and for a thousand generations there are only two classes in the world that really matter: those taking the drug, and everyone else.
One of the powers of the drug is people don't even need to consciously try to signal to others what they are trying to coordinate, the drug does that for them.
This is why Q says their symbols will be their downfall. The symbols are an automatic consequence of taking the drug.
