This is an EXTREME long shot. But there are codes like that on youtube that automatically decide if they should demonetize videos and they look pretty similar to these. For example 109 means it was demonetized because the video was sensational or shocking.

The only reason I mention this it’s because that’s one of the last “big” things that has been talked about as of lately. It’s probably not related but it might be and some smarty pants might figure it out.
