he delivered the info though. It was just useless. And what did you expect?

I don't think he deserves to be called a scammer. I think the buyer was aware that the info he was selling was a useless piece of crap. He paid possibly because he was curious.

I mean if a guy tells you "give me money I'll tell you something really useful". You do, and he tells you whatever. Is he really the one to blame?
