The Cruz paper was demonstrated to be peer reviewed and therefor academic as well both here and at wikipedia.
Which is pretty much what I just said. It's still poor quality, as evidenced by clear errors which even you have acknowledged
Again Journal of the American Board of Sport Psychology is "a peer reviewed journal devoted to disseminating scientific and popular research-based articles in an efficient and timely manner" so your delusions don't matter.
The article does not appear to have been published in the journal. Even then you seem to be unaware that journals also publish non-peer reviewed articles and commentary.
Face it the realible sources and peer reviewed publications are against you. This is reality, deal with it.
Let's say I accept your claims about these books/articles (which for most of them, I don't). Are you saying a handful of articles trump not only a multitude of other peer-reviewed and otherwise reliable sources, but also the actual legal system(s) which get to define this stuff?
Talk about cherry-picking!

Do I really have to start listing the literally hundreds of reliable sources referring to legitimate MLMs as a legitimate business model? Really?
