Wikipedia Revisited

I've checked my wikipedia entry for the false information that I added into the critical reception area on Sunday saying that The Shawshank Redemption won two Academy Awards for Best Actor, Morgan Freeman and Best Adapted Screenplay, though I know that the film didn't win a single Academy Award. It was still on the wikipedia site Monday morning after our class, but I didn't check again until Friday morning and it was deleted. My estimated guess of what happened in the four days in which I didn't check my wikipedia entry, is probably someone from wikipedia erased it sometime during those four days when they saw that it was wrong.
