C. K_findings On eBay / Worst Native scam
Among the scammers on eBay I had no worse experience than Mr. Black Hawk.
He is reselling Chinese made Native costume stuff as Cherokee regalia including certificates of authencity with tribal roll which belongs to someone who couldn't possibly be involved in arts crafting.
You can find exactly same things he sells for sufficient to say 400 times bigger price, if you search with query chinese on eBay!
He also uses hiding tracks so good and sends packages from a P.O. Box which belongs to a technology company in Sardis, Mississippi.
