I cannot understand what do those cheap numbers with payouts like 0.1-0.3$ can really work for? I receive emails from the affiliate company that offers such numbers (they give it for free and than you drive calls and get 0.1-0.4$ per minute). Numbers have some bullshit playing or phone sex or whatever. I understand those numbers could be used by scammers who hack into some voip phones, but even with that they'd bring little to no money. So how do such companies even exist?
