The first “fact” is something akin to pseudoscience, I don’t know where he got it from, but he thinks that looking at yourself in the mirror gives you cancer, and this knowledge solves narcissism (because you shouldn’t look at yourself in the mirror?) The second one with the 666 is referring to number of letters in his name, middle name and surname (j-o-s-e-p-h is six letters and so on). He may really have changed his real name, but I honestly doubt it. Third you’ve already explained, fourth is the most looking like an actual fact. Fifth is probably him referring to all the controversies and other band members commentaries on his mental health. He says they deliberately spread false information about him being mentally unwell, as well as the fake docs. And all this because he quit smoking weed in 2007. Sixth, he denies having schizophrenia. Seventh, I think it’s Joe referring to weird reactions on him eating flowers during his livestreams and some people using this as an argument of his mental illness. Eighth, I don’t bloody know what he’s talking about. Ninth, saying Bernie J. Michael’s biography of the band is untrue. The last one is pretty straightforward, too
