Report video, report player, write to support.
Of course you could report it. The question is whether you really benefit from it. In this case, I assume that the proceedings will be terminated. So personally I wouldn't do anything.
You could first make it clear to him that he is making himself a criminal offense (i.e. Talking to him).
In the event that this doesn't work, you could report the YT video (due to violation of your privacy etc.).
If that doesn't work either, you could report him (to the police).
I don't know his youtube name
He just seemed very unprofessional for an alleged 100k follower Youtuber
Sorry that this might not be his channel, I couldn't have known.
