YouTube is in danger of becoming the video site of last resort if they keep allowing SEO engineers to drive good content down and instead drive garbage to the top
Also, I got my first DMCA takedown the other day. They said I'm allowed 3 before they delete my site. All my videos passed the copyright check when I uploaded them so I relied on that as fair use. It occurred to me that my site will inevitably be taken down if 3 is the limit so I've lost all motivation to use it for anything.
