I believe it may have been in The Independent, @spanfan.
A friend of mine is a photojournalist who attende the previous (and considerably larger) event in London.
He said that the organisers, while coming across as amateurish, clearly had some money behind them.
He described the attendees as mainly a ragtag bunch of cranks, conspiracy theorists and assorted nutter, with a significant far-right element present.
It tallies with what @ticktock19 said earlier about the 'scamdemic group Wig'n'Sleaze promote:
"There seem to be a lot of vulnerable people in there who just need to believe in something (as real life is pretty confusing and turbulent right now) and want to be part of a community and have been sucked up in to it all. They're constantly posting worried statuses about how do they deal with schools / employers and are being told to pull their kids out of the system and not to abide by their employers rules and they should lose their jobs to stand up for their principles.
Prime picking ground for people like Wig and Sleaze which worries me a great deal".
Just like the scammers and cultists, the far-right see an opportunity to draw more vulnerable & confused people towards themselves.
