For anyone who doesnt know ESEA is a competitive gaming league (with a huge number of members) that requires you to pay to get access to their client software. It appears they added in a bitcoin miner ontop of that required fee. Their users are not happy.

I wonder what sort of hash rates they were looking at. Hash rate jumped up a bit around 04/23, maybe that was them? The same amount of hashing power seemed to disappear yesterday. I'm guessing around 10Th/s when you average nvidia and ati cards together for >10000 idle users.
