I can tell you about my experience. I am a journalist, and recently almost lost a lucrative article assignment after a federal agency expressed concerns that I was a “muckraker.” I had no idea what they were talking about. After researching my name on that site (which included several of my articles) I found a way to contact them and have my name and articles removed.
I had no idea what this site was about or that my articles were on it.
OK, that is a serious violation of intellectual property rights. Try to do that with any of the content they have in there that is not your own and they will have a legal team contact you.
