You may feel like being charitable, and that's a good thing. I don't think random strangers asking for funds to be sent Western Union like this is quite the best way to go about it.
We had a member here not long ago from Nigeria (King Shiloh) who played the "good guy" role convincingly in the public sections of the forum. Because he said the "right words," he was getting pretty much everything he wanted for his business paid for by members he approached behind the scenes. Quite a lot of it, as it turned out.
Today's gentleman had all the right lines in place. He was looking for someone to "JV" with, since he can't get Paypal or Clickbank accounts in Ethiopia. He was supposedly willing to do all the work, but needed $60 - $80 by Monday to cover his rent.
Potential payoff, with only a small personal loan needed up front. And a sob story about needing to make the JV work to get to the US to go to college here.
Could it be true? Possibly, but I'd bet real American cash money against it. Every instance of this sort of plea I've seen here over the years has turned out to be fraud.
Please do not encourage these people. We have enough problems with them now, and every person who falls for their bogus entreaties adds to the incentive to tell their "friends" about the marks who fell for their game.
