I have noticed, and have been trying to avoid/report these channels. The Asian guy, even professor Jiang. Theres lots of AI copycats, even Tom McDonald has a fake impersonating channel creating 'Inspired by' Tom McDonalds music. I was fooled until I read the description more clearly. I even noticed that someone re-uploaded one of my most popular videos that I narrated. I didnt report it at the time, but I wonder how many duplicate accounts are doing this...
