If you watched the video, I'll have to be the one asking you — why do you think looking up somebody from your comments section, making them sign agreements under a false pretence and setting up an interview, and then making fun of this individual talking about how "embarassing" he is in your videos is not immature? I won't even begin talking about brigading against somebody when you have a vast user base. Content creators have some unwritten responsibilities and such acts are uncommon because they usually do not fall into these things trying to make "a point".
