Same reason why milesmathis (google it, have fun) isn't taken, and shouldn't be taken seriously by the mainstream. Because "playing by the rules" didn't work - you usually end up with an unending amount of crackpottery in what is actually not published: books, blogs, etc.

Not publishing in the mainstream while publishing books and self published articles is the crackpott's artillery, unfortunately.

Think like the mainstream: given the amount of crazy stuff that's present on the internet that couldn't be published because it was, indeed, crazy, should I care about this particular guy that doesn't publish anything but books (or self published articles) ? The unfortunate answer is no.
