Don't want to distract from this great effort here. Just wanted to mention that having worthpoint and other sites that cache sales has been a major help in tracking down several faked T206 errors. From my small dealings with this, PSA is able to go to eBay and track down the buyers info. Just track everything you have found, dates and screenshot them.
