This is how I see it. Just to say, I don't give a fuck if OP gets a refund or not, and also, I don't give a fuck how this thread will affect the reputation of
@royserpa.
OP saw that
@royserpa was talking about his method and how it's awesome, but for some reason, it's not allowed to be sold here on bhw. However, OP reached out to him and asked questions about it and only after that he bought it for 0.1 btc. Why the fuck would you buy something that is clearly blackhat if you don't want to work on it and later cry for a refund? Why?
I mean, logic tells me that if it's not allowed on blackhat forum, then it's clearly 'more' blackhat than it should be to go public. And if you after knowing all of this buy it, and later asks for a refund because it's not what you expected, then you are the stupid one.
It's up to you, either you want to do blackhat shit or not.
