There is no one “source”. There’s dozens of them. I can’t answer every single question about where the videos are from/where the link is. It’s way too much. I get a dozen questions a day JUST about this, not including all the other questions I get.
I download the videos from many, many different sites after a great deal of searching and I have over a hundred of them currently. I don’t remember where they all came from. I don’t have links to the videos. Sorry.
