Impossible to play online (err 20115)

The DWC_AUTHDATA only contains the userid and some more 0x00 to fill up the 32Byte... So you really only need a valid userid... So i think you could download some old nand dump thats flying around in the internet, if that id isnt banned, providing bans work based on user_id
+ you can login multiple times with the same user id (at least with the same ip, other i dont have tested)
