TL;DR - Jack thinks he's hot shit because he claims he has discord logs from 2017 before Q where someone talks about their plans to post in the way Q posts. Then conveniently, it Q was taken over by other parties (so as not to be provable by posting something in real time) which has now become dangerous - cue Hoover Dam blockade, blah blah blah
Watch embed and laugh at his foolishness. It's probably Jack himself as the disguised figure.
