This is instantly what I thought too. Essentially this guy is teaching how to get rich by using SEO, catchy gimmicks/ideas, and the likes. The spam teacher themselves get filtered, how ironic.
Heh - I wouldn't be surprised if the language used sets off the filter. Machine learning isn't great at abstractions like "writing spam" versus "writing samples of spam someone else might write", so I imagine this sort of topic is particularly prone to filtering.
Yes, welcome to the world of Viperchill - the shadow king of get rich by teaching others how to get rich schemes. I wouldn't be surprised if Google personally targeted him, I would do :)
Sadly this is happening to a lot more people than just me otherwise I would not have written about it.
