Cracking the Absolute Poker Scam
Absolute Poker players began to notice something was awry in August 2007 — newcomers seemed to be having unusual strokes of luck. By September 2007, poker forums were abuzz over a suspicious player named POTRIPPER who had swept an Absolute Poker tournament, winning 20 straight hands in the final round to claim $428,520. When Absolute Poker denied subsequent cheating allegations, several players began investigating on their own, poring over thousands of Absolute Poker hand histories. Player-turned-detective Nat Arem blogged about how he analyzed the hand histories
… I analyzed the lines related to table 13, where POTRIPPER was seated. 2+2er snagglepuss, who I forwarded the spreadsheet to, had already pointed out to me two sketchy observers, one of whom opened up table 13. And when I looked at the data, I noticed something a little weird. One of the sketchy observers opened up table 13 and he was user number 363! This number is incredibly low and I instantly knew that the account had been created by AP or someone who was associated in some way with AP. It had to be a test account of some kind to be made that early in the system. Here's a screenshot:
A Costa Rican IP address (and this IP address becomes more important)
An observer entering the table and never leaving the table until at least 11:20 PM (or over two hours later when the spreadsheet cuts off)
A very very low user number that indicates AP involvement in some way - not that the company as a whole knows, but that SOMEONE on the inside was involved.
