Over on another board, related to cinema, there's a similar guy who is claiming to be making a new King Kong movie. The thing is, he doesn't have any rights to Kong, and his behavior is so grandstanding, he is just going to wind up in court. He is already selling his script online on Amazon, so it's just a matter of time before the folks behind Kong sue him.
Anyway, it's clear that this Kong guy is either very, very young or suffering from a form of sociopathy.He does not know there is anyone outside of himself, and the creatures that inhabit the earth around him are not (to him) fully formed humans, but annoyances which should be squashed. In its extreme form, this is how serial killers come about, but in regular day-to-day sociopaths, it's shown by a contempt for others, and treating others with obsessive disdain. The Kong guy posts gigantic, 10,000 word posts and essays about people who have done nothing more than say "you are violating copyright."
Another great case making the news is the one about the assistant Attorney General in Michigan who fixated on an openly gay HIGH SCHOOL student who won the seat of class president. The AG, in his own time, set up websites devoted to harassing this kid, calling him a Nazi and racist, and then defended his actions on CNN in an itnerview with Anderson Cooper as it all being part of a "political campaignn." The thing is, the kid already won the seat months ago, so there's no campaign going on... and the AG is a fully grown adult, beating up a high school kid. (Here's a link
to the Anderson interview.)
There's another guy who has spent about 20 years attacking the Florida Film Commissioner's office (no matter who the commissioner is personally... it doesn't matter to him), writing nasty letters to newspapers and filing dozens of frivolous lawsuits. He claims to be a filmmaker, but has only produced (get this) a handful of POWERPOINT slide shows featuring his photography. Needless to say, anyone who pops up and criticizes the guy will face a few years of harassing emails, letters, phone calls, and libelous web postings.
I have a business competitor who has, for ten years, run a website which slams my company. His own attempt at starting a company like mine failed, so he became a webmaster instead. He's dropped off the radar in the last four years or so, but the libelous stuff he has posted (calling me a fraud, "the antichrist", a thief, "abuser" etc.) remains there, accessible by Google forever and no doubt hurts my business to some degree. But I understand his motives -- he hasn't been able to build a successful company like mine, and suing him would only bring bad energy to me. So I let him do his thing in peace, and if that gives him joy, I just let it go. Meanwhile I can only work hard and keep my own business running, and my happy customers will overshadow anything this guy makes up about me.
Not ironically, and for some reason, a common trait is that all of these people (well, I don't know about the DA, but the others) are obsessed with their own copyright, and do that "mail it to myself" thing.
So one has to be very careful with these types of people. Continue to monitor what they do, watch for violent language, and report it to the police. Keep a record of what happens, keep emails, take screenshots of things before they can be pulled (and date and time each one), and never respond. Be careful about posting about him here, as you are fueling his need for your attention. Be careful about reporting him to Twitter or his web host, as they always go back to the person for their side of the story, and that becomes a NEW trigger. To him, you may only be a bug (not quite human), but he is obsessed with getting a reaction from that bug. You are the ant under his magnifying glass and for him, the sun is always shining. You just need to pretend its a cloudy day and you just don't give a damn.
When he breaks the law -- and eventually he will -- then report him in silence. No need to report back here (since he is monitoring this, and it will tip him off).
