A posting on the “Team Disqualification” board revealed that a member of Team Ambush had been caught sharing his Battle.net account with a higher-rated player who was not on the team’s official roster for the tournament.

In addition to the disqualification, Blizzard Entertainment will be taking action against the owners of the Battle.net account.

Teams from UC Berkeley and Indiana-Purdue will now battle it out to see which one will go on to take Harvard’s place in the next round.
