Paraskevi Papachristou. A Greek triple jumper, Papachristou was on her way to the London Olympic Games when she tweeted a joke: "With so many Africans in Greece, the mosquitoes from the West Nile will at least be eating some homemade food." The tweet was quickly denounced as racially insensitive, or downright racist, by Twitter users. Greece's Olympic committee condemned the tweet and ruled that she would not be allowed to participate in the games. Papachristou later apologized for the tweet.
