It's nice to imagine but it was probably a copyright bot that logs automated DCMA complaints. In fact I think this might be functionality YouTube provides to large content providers.
I suppose by comparison Bernie's channel would be a "Small Creator" so it would make sense if an Automated System didn't even check who it was fucking with first. Actually, I notice there are at least two Bernie Sanders channels with official Verified status on YT, I wonder what that means?
It's region blocked EVERYWHERE near as I can tell. France, Egypt, Hong Kong, Ghana. I know youtube is just one video platform. But the power and reach that NBC universal has is goddamned disturbing.
