There was a case on YouTube where a (sort of) satirical YouTuber Reactor (a fake over the top reaction channel) used a cut up footage of GradeAUnderA hating reaction channels as an ad on GradeAUnderA's own videos to direct people to Reactor channel as part of a scheme to bait GradeAUnderA (a 2-3 million subscribed channel) into attacking his small channel (1-2 thousand subs post these antics, much more later after the scheme came to light) to "expose" him for being a bully, starting fights (despite saying how he hates them and how they ruin YouTube and attacking people who are having them) and so on.

What a quagmire, I know.

Good video summarizing it: https://www.youtube.com/watch?v=H9_6UCkxu_U
