Few other cases like that escaped the social networks and became a direct danger to real people. Few got politicians to display signs they agree with the conspiracy ideas on public TV.

They sound like glorified shitposters that escaped the confines of /pol/. Are they really causing that much of an issue to FB and other platforms?
FWIW I read the article, but it meanders a lot.
