The world filter on the PS3 chat is my favourite example of this. It was almost impossible to chat with friends during gaming session when for example "Akuma" (A Street Fighter character and a perfectly safe word in Japanese as well) gets censored into "a---a", and Several Finnish words like "pelata" (to play. "pela" is something offensive I guess?) "mutta" ('but'... apparently it considers "mutt" a bad word.) and anything containing "ass" (ssa is the inessive suffix and Finnish has vowel harmony. Fun.) and lots of others get completely mutilated.
