Muta is a leech who feeds on drama, but Carl is the part that confuses me. Why him? He's an autist who talks about speedrunners, not a king-killer.
I can think of two potential answers to this.
First, while Karl usually talks about speedrunners, he was also the guy who got people looking at the WATA Games/Heritage Auction price-gouging scam. personal example but whenever I mention Jobst, that coverage is the only thing anyone knows him for.
But this leads to my second theory: Like you said, Jobst usually covers speedrunners. Scams aren't really his thing.... which ironically means that when he
does cover one, its a bigger deal. If Mutahar covered this by himself, as a guy who covers controversy routinely, it might not have gotten any attention, but the fact
Karl covered it probably gave it more legitimacy in people's eyes.
To use an autistic analogy: If Batman says someone is criminal scum, that's just Batman being Batman. If
Superman says it, then its probably true. (If you'll forgive me comparing Karl to Superman).
