I've had my Skype on for the last few days and every now and then a message pops up from someone I don't know. Almost nobody knows my Skype number, so I don't know how they do it. Anyways, I just got a message where they were promoting e-cigarettes and had a message/link to their affiliate e-cig page. Is spamming Skype a viable way to affiliate market? It can't cost much, I assume. Do these guys just have programs that somehow get Skype usernames and spam away? If it's just a program I don't see why everyone wouldn't just do it, in addition to whatever else they have going, and run the program in the background.....but I'm maybe not seeing the whole picture.
