I recently worked a case involving, among other things, Armslist scams. In this instance, the "seller" was nothing more than a middle man, who received money and forwarded it to Nigeria.
The actual poster, using the middleman's name, would post photos of typically very nice guns gleaned from the internet, and handle all correspondence. I was able to track well over one hundred thousand dollars funneled through this one individual to Nigeria. The middleman, while having little knowledge of what was actually transpiring, was left holding the bag and is facing 20years in prison as we speak.
These case are terribly difficult to work, but very rewarding when they do pan out.
