You don’t know Sergey Galyonkin. His childhood in the Ukraine, his Olympic success, his life in Cyprus, his work behind the scenes at Wargaming. All this is of no interest to you – and why would it be? But what Sergey does in his spare time – a persona called Steam Spy – has developers hanging on his words and with good reason. Steam Spy has used loopholes in the Steam community system to drag hugely interesting and valuable game data out of the network, package it up smartly, and give it away for free.
