What sport at the 2012 Summer Olympics saw four teams disqualified for "not using one's best efforts to win?"

Four women's badminton pairs from China, South Korea, and Indonesia were DQed for not trying hard enough. While they insisted they were trying to pace themselves, energy-wise, it was alleged that they were actually trying to tank their early round robin games in order to get easier match-ups in the subsequent knockout rounds.
