It really doesn't surprise me that there would have been people saying crazy things, however, I wouldn't even know who the guy was, if not for parts of the British media going on and on about him (even after around fifty years). And honestly, I doubt anyone else would either.
We also have to ask whether part of the media's fascination with this strange guy played a role in the rise of QAnon like ideologies (a form of far right extremism) in the U.K. The guy himself has always been an irrelevant figure but the media's reporting on him might inflate his perceived relevance.
Also, whether it's Savile or this weirdo, it felt like outlets like Vice World News would try to make these sorts of things the world's problems, despite really being British matters.
