And here's the bad news...
There are enough clueless people out there that these guys will, initially, probably make some decent money. Ebay needs to shut that crap down, and these guys should be investigated by the feds for fraud, and... well whatever else they can find. I'm pretty sure advertising your services as a mercenary isn't fully legal.
I'm sure this won't go unnoticed, and these morons are in for a sh*tstorm of trouble.
And a well deserved storm it will be.
