The website listed on the BNP page are neither anonymous, nor personal websites. The External links policy clearly states:

Links normally to be avoided:

A page that contains factually inaccurate material or unverified original research, as detailed in Wikipedia:Reliable sources.

And the Reliable sources policy clearly states:

A self-published source is a published source that has not been subject to any form of independent fact-checking, or where no one stands between the writer and the act of publication. It includes personal websites, and books published by vanity presses. Anyone can create a website or pay to have a book published, and then claim to be an expert in a certain field. For that reason, self-published books, personal websites, and blogs are largely not acceptable as sources.

Not only is MNP a personal website, it's also blatantly anonymous. Still, I'm going to wait for your reply because editing. Perhaps I misunderstood something.
