Why shouldn't he?
I mean, you have argued that even if a crime hasn't been committed it doesn't make it alright but that is your morality and you are free to unsubscribe and never watch him again. Even the racist texts are a matter of personal morality. I know people who say racist things sometimes and I express my disagreement, but it doesn't nullify their humanity in my eyes. They have redeeming characteristics even if they might be ignorant in certain areas for various reasons, discerning between correlation and causation being the big one.
Even the point about using their 'status' to appear more attractive is moot as far as I'm concerned. How many people join bands to appear more attractive? Hell, even Sartre said something along the lines of his becoming famous and a philosopher was to attract women. He became a thinker when it dawned on him at an early age that he was classically 'ugly'.
None of this makes stalking okay, and it is a crime. None of this makes being sexually inappropriate with underage people okay, but that is also a crime. As others have said evidence...innocent until yadda yadda yadda.
If the accused is convicted then removing him (or her) appearances is probably a wise move, maybe a necessary one. Until then, he's going to film himself talking about theme parks.
Okay, he has a platform with young people, but if it's just him and Charlotte from now on, that's all he can do. Until he starts being overtly critical of Black Mamba for no apparent reason there's not much more that can be done other than individuals deciding that they don't want to watch this person anymore. Even then, I'd put it down to an inferiority complex...
