I'll be honest with you,I have a fair idea of what you "scam guide" was.But anyhow,you sold him a method,he complained about it but is now making money with it.If you refunded him then he had scammed you,if you didn't refund him then there is no problem.That is the problem with ebooks and why I think they are a pretty bad idea to be sold on this forum.So the question is,did you refund him?
I'm bored to update this post, but I've found that he uses 5 BCT accounts to scam people.
I don't see why would I refund someone who can't use google search. That's what 5yo kids being taught when they get on the internet for the first time.
Are you Brazilian, by any chance?
