This obsessive piece of shit is so dumb I'm having a hard time believing he's a real person, and that this isn't some work of fiction for Reddit's Pro Revenge section. That being said, if we are in fact dealing with someone who's an idiot on this big of scale...then damn. Sounds like this bully was long overdue for his demise. The fact that he served it to himself makes the story all the better.
If you're looking for more pro revenge, we recommend checking out a classic story of revenge, when a meathead mercenary tried to go after the IT guy, and ended up getting his in the end.
