I guess that freedom 251 phone is one of the most successful large scale black hat methods. -Make some average looking landing page. -"Offer" smartphone with some budget hardware for $4 -Build hype by making people reserve their slots in order to be able to buy it -"Launch" the product -Get over million orders, collect money and say you are out, giving people hope it is still legit and that others will be able to buy it soon -Profit and disappear with millions of dollars I actually do not know how they even managed to get that amount of orders for a phone which does not exist. They changed 3 different designs of that phone 1 day before "launching". In some videos there is one phone represented as freedom 251, but it is actually some other more expensive device with a bit of white paint over the logo. Overall, really poorly done, but since people are stupid, it was a huge success for creators.
