The translation function isn't really usable!
Most of the time you try to translate a text out of a forum you get the answer "This request violates our Terms of Service."
Even if a book is recited. Why? It's a translation!!!
Maybe the original text violates the Terms of Service. But to recognize that I (specially I, not your Service) need the correct translation!
A translation service should do exactly what it's name say: translate everything . Otherwise it's useless.
