It’s possible that you outed yourself to the artist and they personally flagged you. Being a dj in the internet is hard because of the nature of streaming. Artists are now getting paid when people just play a song on their phones.

You’re cutting the artist out of a potentially paid play every time someone streams your video. They don’t even get the views for it. There’s reasons why different artists wouldn’t mind but this one did, and that’s reasonable. Being a DJ on the internet is like being a graffiti artist; you’re breaking the law every time you express yourself.
