A user on the SteamRep forums who goes by base64 has potentially uncovered evidence of organized Team Fortress 2 market fraud (opens in new tab) . On Sunday morning, the community investigator noticed an unusual jump in the price (in TF2's common currency of Keys) and volume of Earbud trades. Earbuds, if you're not familiar, are an especially valuable TF2 item. Further investigation revealed that the Keys used to purchase the Earbuds at an above-average price had consecutive or regularly alternating (odd or even) original ID numbers, which indicates they were likely purchased in bulk directly from the Mann Co. Store.
That brought up questions, like, say, why would someone purchase thousands of Keys for $2.49 each, trade 28 to 30 of them at a time for Earbuds, and then sell those Earbuds for 700 Russian rubles (opens in new tab) , for a loss of about $47 each? Base64's thorough investigation can only lead to educated speculation, but it's all very suspicious.
The big drama version of the story is that Russian mobsters are using Team Fortress 2 to launder money. Since this isn't a Neal Stephenson novel, the more likely story is that someone's sitting on a few stolen credit card numbers. Some SteamRep posters say base64's research reveals "nothing new," suggesting that this activity is commonplace. Whatever the case, credit to base64 for uncovering so much via Valve's API and interviews with Earbud sellers involved—if nothing else, it's a fascinating study of digital forensics.
