I see people uploading porn on this public ftp in my country which is mostly filled with warez. They password protect the supposed 'movies' and add a TXT file which tells them to send a SMS to a certain number in order to get the password. They never receive the password, of course, but they are charged some money. I can't seem to find services, which would provide affiliate programs for signing-up via sending SMS. I'm thinking that if I can't find this kind of an affiliate, I could make the horn-dogs sign-up 'to get the password'. Sorry, if this this a noob question and flame me, if I haven't searched the forum properly before posting this.
