8. Olympians expelled for racist tweets and neo-Nazi ties
Olympic athletes and coaches were sent packing from the 2012 London Games for an array of reasons. A sailing coach was disciplined for drunk driving, a judo fighter tested positive for marijuana and a rower was punished for a booze-fueled rampage.
At least two athletes were expelled for sending offensive tweets. Hours after Switzerland lost to South Korea, Swiss soccer player Michel Morganella said in the tweet that South Koreans "can go burn" and referred to them as a "bunch of mongoloids." He was promptly sent home.
A few days earlier, Triple jumper Voula Papachristou was kicked off Greece's Olympic team for her comments on Twitter mocking African immigrants.
Addressing the reported appearance of Nile-virus-carrying mosquitoes in her native country, Papachristou wrote: "With so many Africans in Greece, the West Nile mosquitoes will be getting home food!!!"
The following week, on August 3, German Olympic officials said that rower Nadja Drygalla had left the Olympics after a broadcaster reported that her boyfriend was a supporter of an extreme right-wing party in Germany.
Drygalla, a member of the women's eight crew, left the Olympic village to avoid any "burden for the Olympic team," said Michael Vesper, general director of the national Olympic association.
According to Yahoo Sports, Drygalla's boyfriend was reportedly "a leader of the Rostock National Socialists, a group German intelligence describes as neo-Nazi and racist."
