Attention fraudsters!

I assumed correctly that the "2" feedback score on the shilling account is from the same seller, who left himself feedback on 2 recent transactions.

Since Ebay's system anonymizes slightly different each time, it acts like an inefficient fountain code

Combining information from the 24 listings, one can piece together an anagram of the shilling userid: fr113356789

(may or may not contain double 1's or double 3's)...

I suspect ebay's userid scrambling code/polynomial is related to the item number, if anyone wants a good puzzle to write a "decryptor" for ebay's obfuscation.
