If not that, then that 5G mysteriously hastens the transmission of the virus. [...] Celebrities like Woody Harrelson say "the negative effects of 5G" are something worth considering, when talking about coronavirus. Back in the UK, Amanda Holden, best-known as a judge on Britain's Got Talent, shared a link to a petition with her 2 million Twitter followers, calling for more attention to be paid to the idea that 5G is driving Covid-19. The petition and the tweet have been deleted, but not before The Register published this memorable report in its characteristically searing style.

The Daily Beast has done the unglamorous chore of documenting the madness.
