I really don't know what you want here, my man. You're asking for irrefutable proof when no one can provide it. This is a curious set of events, not a legal case. If they had the proof you want this would be a much bigger story wouldn't it?

Your YouTube comment specifically makes no sense, copyright strike on what material? Also, didn't you just said that "shadowban" happens all the time? Now it's never been seen before?

Again, I have no idea what you want here.
