Usually in badminton, or any other sports, the objective is to win the match and proceed to the next round. However in the 2012 summer Olympics, Two South Korean, one Chinese, and one Indonesian team decided to do something different. It is feasible to the qualified teams in the round robin league to lose a match in order to face a weaker opponent in the next round.
These teams decided to do the same thing and purposefully tried to lose their final round robin matches in order to secure weaker opponents in the knockout phase. However, the World Badminton Federation saw this behavior as unsportsmanlike and disqualified them from the games, despite their protests.
Everyone who follows long distance running in Olympics knows who Paavo Nurmi is. The legend won 9 gold and 3 silver medals in 12 events in Olympics and set 22 world records in distances between 1500m and 20 kms. However, during the early days, only amateur athletes were allowed to participate in the events.
Nurmi was accused of accepting too much money for travel expenses for the 1932 Olympics and disqualified him, as he had now become a professional. He never participated in Olympics ever again.
