Honestly, I think you're underestimating the situation, which is odd considering Chit's numerous disturbingly in-depth essays on Chris.
People post bad fan fiction on the internet all of the time. Very, very few are trolled as badly as Chris. Most just never get any views. The simple fact is, most self-identified trolls don't really have any skills besides convincing themselves that they're cooler than they really are. They flock to Chris because he's the lowest common denominator. Half of the time, you don't even have to DO anything, you can just read Sonichu & you'll get all manner of details about his personal life. You post those on his Wiki, he gets mad, he makes a bigger ass out of himself trying to counter what he initially wrote. The cycle continues indefinitely for easy infinite e-peen growth.
What actually started the trolling in its current form, the form that changed Chris forever, was that he was just such a goddamn
odd person with such immediately identifiable connection to Sonichu.
See, Chris doesn't have much of an identity. Most of us identify ourselves based on our personality, what we enjoy, who we love, things like that. Chris's identity is based on tangible things, a sort of caricature of himself. His red and blue striped shirt, for instance. Or where he went to school. One of the reasons he tended to give away so much personal information during the Liquid Chris saga was because he thought that by telling people things like his phone number and home address, he could prove his identity. Some even believe that he gave up the iconic clown shirts not because of changing tastes, but because he thought that it would make him less identifiable as Chris-Chan. It's much like how cartoon characters only have a few outfits in their closet; viewing Chris's personality through a comic or cartoon filter leads to much of him making much more sense.
Part of that identity is Sonichu.
Sonichu the comic is the closest thing Chris has to any kind of accomplishment, and he legitimately thought that he could get fame and fortune through it (despite his unwillingness to actually put forth effort; he just figured he'd hand the property off to Nintendo or Sega or whatnot and get royalties). Sonichu was such a huge part of his identity that it was essentially part of him in a sense. Hence why he wore the medallion and talked about it any chance he got, or worked Sonichu into other works or projects whenever he could.
That's what led to the initial trolling: his connection. The first Sonichu bits and pieces show up on 4Chan, and people laughed their asses off. But because Chris had connected Sonichu so closely to his identity, many people who knew him in real life knew about the comic. So when a couple of GAMe PLACe regulars went on 4Chan and saw the Sonichu comics, they snapped a photo of him and uploaded it with some more explanation of who he was.
And so it began.
