He has actually been issuing DMCA takedown requests for ages in an effort to remove the old videos that prove he is much smaller than he claims. He clearly didn't anticipate his videos coming back to bite him in the ass. Guy is a sociopath too, barely worked a day in his life. Mostly lives with his mother (the poor woman) and is in his 50s. Just been riding his lie and taking handouts.
I say this in the kindest way about Jonah; often the biggest liars would have been better suited to become fiction writers. If I recall correctly, I read somewhere something about him being a talented writer, or actor, or something like that. If he were a bit better at separating his fantasy specifically into fiction, and not insisting on parading around the lie between his legs, he'd have been able to make a good living from it.
I don't think they start out attempting to be malicious or with the kind of sociopathy where someone would harm someone else for fun or take pleasure in another's suffering. Many people who are mentally ill never move out of their parents home. I think this particular mental illness stems from a disillusionment with the mundane reality they live in. Autism may be involved too.
These guys come up with a fictional character that has the attributes they'd desire, from being an undefeatable champion fighter, to the guy with the world's biggest crank. They are so invested in it they end up playing this out in real life.
Frank Dux is a good example. The guy is now well known to be a fake martial artist who made elaborate stories, some of which have been turned into movies. The vast majority of traditionally published, let alone self-published, authors will never have their works turned into a movie.
While "biggest peepee" alone isn't all that creative, Jonah has all sorts of additional stories about famous women who sought him out for sex. It's a fantasy I could see doing well in fictional form.
Instead of writing their best seller about the ninja special forces secret agent with a giant penis, they instead try to convince the world they really are that guy.
