A question I asked before and never really got an answer, what is the benefit of spam? Surely the people who take the time and effort to set all of this up must be doing it for a reason which I assume has to be financial gain. If someone could just simply explain how this converts to money I'd love to know.
Spammers are selling something, be it fake drugs, access to porn channels, dodgy inheritance offers, access to sports events, and so on. That's how it converts to money.
Idiots respond to the spam, buy something using credit cards, then they lose more money as their card data makes its way in to organised crime.
