I don’t know about this one, but we had a group of these around here a couple of years back. They largely flew under the radar until their leader one day decided enough was enough, marched to the nearest military based and asked to see the commander. She then handed him a list of people to arrest including the president, every member of the government and a couple of other high profile people. In comparison that the screenshot seems fairly tame, so I’ll believe it.

They’re very real. The posts I’ve seen in the various groups I’m in are wild.
