Poor Joe,
luckily it was just $1000! Think about asking him/her to bring 10 times that!
I have been scammed 2 years ago and I can't publicly say who the scammer is. I met that scammer on a reputable Website such as this forum, and other members of that site were scammed like me and contacted me in private to share their experience, but this hasn't stopped the scammer - indeed! I felt angry at those scammed before me for not posting a warning, and when I tried to warn other anonymously, all I got was blackmailing and insults in private perpetrated by the scammer.
So - what's the point of airing out your experience if no name is provided? The scammer's modus operandi might vary from victim to victim, the only steady thing will be the scammer identity.
If the first victim spoke out, there wouldn't be a 2nd, a 3rd and a Joe.
I don't think you'll ever see your money back, but I hope you will be able to cause the scammer troubles when he/she tries to enter Argentina or Uruguay by filing a report against him/her.
Anyway, I suggest you to believe in karma rather than the police.
