You'd think that a team competing for a $15M prize would know better than to use anything that can remotely be considered cheating.
The Thunder Predator team was taking part in a qualifying match for the Dota2 International that offers the massive prize pool. It was disqualified because a player called Atun used a programmable mouse that let him speed up in-game actions. Thunder Predator denounced the ban saying it had not used a "hack" to win.
