I have a new tab on the left side of my YouTube Studio. It's called Content Detection. I have seen that on site that I have written posts. I was very happy that the site was scouring the internet for people who was stealing my content, but it was like playing whack a mole in trying to get the content removed. And I hated that we had to provide our real name and address with the DMCA notice. (I use a pen name there).
Anyway, I am glad that it is there and hope that it isn't as easy to steal a video as it is to steal an article.
