CTG is an internet troll and the psychology of internet trolls is reasonably well established. Happy people don't troll. Trolls use people's reactions to build up a false identity to cover for their real issues with themselves. If you starve them of reactions, they will need to look elsewhere for a magic identity mirror (or actually deal with their issues).
What separates CTG from your run-of-the-mill troll that feasts on hate is that he appears to genuinely love Stunts. He spends a significant portion of his spare time managing competitions, racing at a high level and creating original content. Why he constantly tries to manipulate the only community in the world that shares this passion with him is a mystery to me.
I don't think all trolls feast on hate. They come in different shapes. Some use hate speech, some use provocation and some use impersonation.
But you're right that he seems to enjoy Stunts.
Of course he's about to ejaculate in his pants from all the attention he's getting right now, so for now we're only feeding the troll. I don't mind CTG's Stunts-related posts, and some of his off-topic posts are also just fine. It's only the disproportionate amount of them, and the insulting and the repetitive ghost-creation and ghost-spamming that's throttling the community.
