Didn't that guy from Adema die? That sucks. That song is awesome everytime I hear it I instantly think MK. So much better than that shitty rap song in MK X lol. But anyway, not surprising. They screwed over tons of channels lately with their new policies, that killed monetization, like most social sites owned and run by super liberally viewed people. Some snowflake probably got offended by some MK content or it's deemed "too violent" something lame. Kind of sad, thought we were past this with the 90's and media blaming MK for things now YT has to mess with MK?
If anything, they could just have it be required to be marked as Age appropriate rating like other vids out there or create a section for rated M games.
