thing is that, when someone report about scam, they don't do anything about it instead of investigating about the issue. probably just laughing behind the monitor.
they should have provide a payment system to avoid such transactions.
Again - I agree that eBay is not the most proactive or well policed market place; then again, they have millions of items advertised in hundreds of categories and thousands of vendors residing in dozens of countries, and they charge peanuts for their services - try selling through Sotheby's or Christie's and then tell me.
The transaction itself is not illegal. It's the use that someone else - NOT eBay - makes of the document after the sale that may be illegal.
