64bit not allowed since today

since today the 64bit client and every client modification is not allowed.

Of course GF cannot check my client for modifications like NA pack but can they detect the 64bit client? is it sending different information that can be a hint for GF that u are using the 64bit client?

no they cannot detect it

They removed the forbidden rule about 64bit client due to the massive request to let use it still [in case that you need to use it :D]
