To understand Youtube a little better, you have to depart from the so-called "gun community" and look at the bigger picture. For Youtube to "monetize" a channel means they hand out cash for "views" and "subscribers." It doesn't take much imagination to recognize that's going to be "gamed." There are entire enterprises devoted to automatically creating channels, using software to generate new videos without human labor or intervention, and using banks or farms of virtualized computers to subscribe and watch them. Search on "finger family" and you'll find several nursery rhyme channels with over 22 million subscribers and single videos with over 1 billion views. These are not pop music videos. There are other channels with over 100 thousand videos uploaded (representing over 10 years of video play time). A quick search pulled up a "this little piggy" video uploaded 3 weeks ago with 2.7M views. These only represent the most rudimentary efforts that were realized many years ago. Since then, the whole game has become far more elaborate because naturally, Youtube is going to make an effort to identify channels and videos that get real people watching them with enough interest to tolerate targeted ads because ultimately the advertisers are going to become savvier and not want to pay for bots to watch their ads.
The bottom line is not to expect monetization from Youtube unless you're willing to make a tremendous effort to not only produce good content and cultivate a valuable audience but also to be recognized as distinct from the many scammers. There may be an impression that Youtube doesn't favor gun-related content or that they even persecute gun-content creators, but you can bet that what the company is even more actively working against are the ones trying to rip them off. Youtube gets paid the cash money that it generously favors by the NRA, USCCA, "Modern Barbarian," "Tactical Traps" and on and on... Just click around popular gun channels and watch all the targeted ads from money-paying advertisers that Youtube is not about to turn away. I can assure you they love money more than they hate guns.
