Believe it or not, we're getting about the same number of views as ZombieGoBoom gets on many videos at 1.7 million YouTube subs. They've even begun putting the monetization icon in the thumbnails. That's how badly they are demonetized. #adpocalypsehttps://twitter.com/leonardjfrench/status/972034689849548800 …
There is one possibility I can see and that is age gating due to dramatised (sic. I am from the UK) graphic content which is in there. I had one video age gated and that was also automatically demonetized. Could this be the reason maybe?
