It doesn't matter either ways really.
Assuming he's the real thing - He's likely similar to the person who made HYBRID. In this case we should probably feel sad about his plight, but if he does indeed have the tremendous level of tenacity that the guy who made HYBRID has, then he might actually be able to not be a complete loser and manage to complete his claim, and we'd at least have a bad example of things we can show others what NOT to do. (Though I personally doubt that he'd be one, but we'll see.)
Assuming he is not, and is actually "that guy" - In this case he is just some sad excuse who can't let things go even though he was the one who started it all. - And of course he didn't think so, didn't realize how much crap his own action made, and would think he's the one who got a great idea and we were the ones who ruined him. Self-reflection just isn't a thing nowadays I guess. Well, if he's any good at taking responsibilities he wouldn't have done the whole thing in the beginning, or dealt with it so badly after he got caught. - It kinda proves that he's everything we've known him to be by doing this, and if he wishes to continue to be a laughting stock... Free entertainment is free. v(owo)v
Assuming he's some other guy who thinks its a good time to milk a joke - He's pretty much harmless due to how obvious he is. He's not gonna change a thing here or anywhere. People with half a brain won't take him seriously. People who would take him seriously would probably be ruined, but its the internet and the internet is inherently cruel and heartless, and one can only be responsible for oneself. (Not like IRL is any different, but the www is just more obvious.) And eventually he'd run out of steam, cause his underlying drive isn't about what he likes... If he can keep his drive going forever, it makes him even sadder, but again self-responsibility and all that crap... For now, again, free entertainment is free? v(owo)v
So... Whatever.
Do what you wanna do, I say.
