i can guarantee that the 7 video did inspire quite a number of people to start to confront banny about his toxicity, which, giving banny's stubbornness to others' viewpoints (especially about himself), would have led to harassment since they would feel like banny isnt listening to their seemingly good-hearted words. (I worded that kinda terribly but I hope you understand)
Just because you call out someone for being bad, doesnt make you automatically good.
