@loyhena Thank you for the information.
I thought about this eventuality and I thought I was cautious by visiting https://en.wikipedia.org/wiki/PewDiePie before posting, but quickly haven't found any "controversial" chapter and after quickly browsing, I thought the guy was more or less ok. My error. I probably should have read all the long page ( now I see it: https://en.wikipedia.org/wiki/PewDiePie#2017%E2%80%932018:_Media_controversies,_streaming,_and_formatted_shows ). A proof I don't know really the influencer except of being a "famous video game YouTuber". My bad!
