So a few mates of mine who work for local venues/promoters were chatting about this on Facebook today.
Totally bizarre story.
Basically "Threatin", an american metal band is currently playing a UK tour, but nobody has actually heard of them, and all their "fans" seem to be fake account online etc. Very bizarre as they've probably spent £30k on booking the venues etc :/

Seems like a musical equivalent of Tommy Wiseau's The Room
