I was referring to Facebook with my comment, not Diablo 3. Facebook massages the data to allow you to login even if you have caps lock on, so "pASSWORD" works when your password is "Password", or if, e.g., your phone capitalizes the first character in your password, so "Password" works when your password is "password".
