I found the link the the thread about the fake cards from 2005:

Notice the familiar pattern of attacking me personally, calling me Mr. Ryan, discussing what I've bought in the past, using several aliases and different names, etc. I suspect that it's possible the people that tried to pass off those fakes as real are the same people we're dealing with now.
One of the first red flags for me was when I look a "seller's other auctions" on ebay and saw all those fountain pens. EXACTLY what the seller of the previous fakes ("Polar") specialized in on ebay. And suddenly there's a newer eBay account with a feedback rating of only 41, who also specializes in fountain pens and items from Cuba, just like the Polar seller. And they come on Net54 and sound exactly like the previous scammers and use the same tactics such as personally attacking me.
It still doesn't mean that these are fake. It's possible for real cards to be discovered by unethical people. But the seller's current behavior probably isn't building anyone's confidence about the legitimacy of these cards. There are other red flags I will post about shortly, but anyone who reads that entire thread about the fake Polar cards will find it extremely similar to this one.
