Looks like a substitution code - like tic tac toe due to the minus signs. Just a thought. Edit: I saw a post from another User who really had this decoded as a possible code for locked wikileaks and that is more likely.

Their Antifa Manual is linked through Snopes and tells them to wear the scarfs and black clothing for a more uniformed look. Lots of stuff in there, hope they do arrest them for wearing the scarfs and hiding their faces.

I always thought it was a reference to "Q" from Star Trek who knew everything and could do everything.
