Well said Wabbit. For all we know, the guy could have got killed, lost a job, family member died, got cold feet, got contacted by the IRS & told he owed back taxes, fallen off a cliff, went to the sanitarium, or just packed up & joined the Peace Corps.... who knows.
There is no scam. I am sorry; but this is a "scammer" forum. That is why people here have said what they have blackpearl... they are not giving you a hard time, they are considering all the things that could have really happened in this one-sided-scenario. JMO!!
