>will the fires come to a stop now that arsonists know they have been monitored?
yep.
Strategic detail:
Q dropping 'Signal.org' on /qresearch/ is going to go through Antifa like wildfire because it matters if they get arrested.
What will this cause?
Get ready for a huge chunk of Antifa/BLM useful idiots to suddenly follow Q.
>or just go home?
they'll just go home, but since Q was the source of the intel on Signal, they'll implicitly want to know what else is coming from Q.
