Yes, absolutely, all of them are scammers and con artists, I have researched Skyes - he did really made money during the dot com book, created a hedge fund after that and lost it all. Reinvented himself as "educator" and he is making money from teaching and also from front running his followers (buying low float stock, telling his followers, and selling into the spike they have created following him - this will not happen with high volume stock BTW) for the other guy, never heard of him, but you can check here to see if he is been exposed already:

Bottom line, there is no easy street to the stock market, if it was possible to pay someone few grand to learn how to trade and make money every month, everyone would be doing it already... Realistically you have to plan to spend few years learning and testing different strategies until you find what work for you and start trading with real money... It is not that different than being a lawyer, dentist, doctor or engineer - you cannot do it in a year with a few online courses...
