What began as an April fool’s day joke, the code ended up mining as many as 29 Bitcoins worth over $3700 for ESEA league in a span of two weeks. According to Eric Thunberg, one of the League’s administrators, the mining code was included as early as April and tests were run for a few days after which they “decided it wasn’t worth the potential drama, and pulled the plug, or so we thought.”

The code was discovered by users after they noticed that their GPUs were working away with unusual high loads over the past two weeks. After users started posting on the ESEA forums about discovery of the Bitcoin mining code, Thunberg admitted to existence of a problem – a server restart for “a setting getting changed which enables it for all idle users.”

Initial assumptions were that the code didn’t mine more than 2 BTC but, Thunberg revealed that the mining software had successfully mined 29 BTC. Thunberg said, “This is way more shady than I originally thought, and as the person who is ultimately responsible for everything it’s 100 percent my fault.”

Users vented their anger on the ESEA forums claiming that their video cards were maintaining over 90 celcius+ temperatures for extended period of time following which they have started getting video errors. Some have also accused ESEA of damaging their video cards.

ESEA is now trying to appease the irate customers by offering one month’s worth of premium membership for free and has also promised a client update that would strip off “all the btc stuff.”
