I should note that Youtube didn't give me the option to list my video as either 18+ or otherwise do something to make it work. They simply didn't want my video there. Its no more graphic, and actually much less graphic, than many other squirrel videos out there. I think they removed it simply because the video was too popular and leading too many people to my channel, and it would be obvious to anyone that even though I don't discuss politics on my channel, I fit a demographic profile of a kind of person that the leaders and employees of Youtube/Google don't like. Hickok45 gave Youtube quite the spanking when they tried to ban his channel twice this year and his fan outcry made them bring it back. I wouldn't be surprised to find out that Youtube is trying to limit the growth of voices it doesn't like. The removal of this one video has deducted 102,000 views off of my viewership tally and has lowered my daily watch time stats by 30%. Something about Youtube's algorithm made this video sizzle, and also put it in front of a lot of anti-hunters. I think the popularity killed it. I now worry about my other 100k+ view videos getting arbitrarily deleted.
Also of interest is the fact that the day the video got flagged and removed, a foreign hunting channel uploaded the same video as one of their own videos. They would have had to have copied it before it got removed, and it would be an amazing coincidence that they copied and posted my video right before its removal from my channel. Things that make you go "hmmmmm." I reported the video for copyright violation and Youtube shut the pirate channel down, although they sill refused to reinstate my video.
