That is what happened on Jan 6th. There was a blackout at The Donald. You needed captchas to enter and even if you did enter everything was really slow and the site was crashing regularly. If you managed to get to the new posts section of the site you would see that all the posts were calling for riots and all comments that disagreed were downvoted to hell. Also there were "fuck trump he betrayed us" posts when he posted the tweet and the video condemning the riots. Im sure a reasonable amount of frens fell for the posts and were agreeing with them but thats peer pressure for you. Its hard for most people to think for themselves. Needless to say when the attacks faded away people started thinking more clearly and realized it was mostly antifa that breached the capitol... So who was making the posts that called for civil unrest? Some guys that were sitting behind their computers.

P.S: The accounts that called for radical actions were not new, so it was all planned.
