It's still going on and is worse on eBAY. Today (3-12-15) I managed to get a customer rep at eBAY, who acted as though just hearing about the shocking fact that 95% of the high-capacity (> 128 GB) thumb drives on eBAY are fake. This is bleeding edge tech, so it's not like 20 yo camera lens somebody found in the attic, and so can be real eBAY deal. There are no real deals on eBAY for this. Google a reputable seller like www.newegg.com.
There are two examples of 2 TB (2000 GB) thumb drives being auctioned on eBAY today! The problem is nobody on earth makes one that large. Kingston makes a 1 TB but it's large and bulky and $1000. You can get a fairly bulky real 512 GB from Kingston or Corsair, but the minimum price is $350. Everything below these prices for both thumb / flash drive capacities, are counterfeit. In the case of the "1 TB" and "2 TB" HP metal pen thumb-drives (with the hasp-like thing), these are actually 32 GB pen-drives repackaged in fake or altered packaging.
HP doesn't have their name on a drive larger than 128 GB at this time.
Here's a rather horrifying article about the many software scams that go along with the fake drives to make them look at first like they really have the rated capacity:
