I don't know anything about this. What is amazing is that this guy has 80k subs. I remember when he started, it was only a year ago or so. He must be doing something right, but I can't for the life of me figure out what, other than having a sportsbike.
As for the donations stuff, I read the altercation on the video. Starts off questioning, gets all pally-pally, then sick goes off on one. Impossible to see what actually happened but, you know what, I don't give two hoots.
If anyone is daft enough to believe that someone's word is their bond, from someone who they only converse with on YT, then that is their own fault. Lesson learned - don't believe everything you read or hear on the internet!
