I can't remember where I read this. It might have been a Q post, or an anon's commentary. But the reason Q posts in brief, minimalist bursts is because of algorithms that can identify a person by their verbal usage and syntax. So he "speaks" in a way that most assuredly is NOT the way he would sound if he were talking to you or writing you a personal note.
Obviously, there are many deep state figures in the CIA, NSA, FBI that want Q dead. As Q says, "This is not a game." Very dangerous business.
Moreover there are reams of analysts scouring every detail trying to bring them down.
Q messages are to us, the public, and some are to assets who are engaged in doing things, and some are directly to the bad guys who are also reading all of Q messages.
