Question as above. Does anyone know if it possible to deactivate the supposed recommendation option in game center which looks to your contacts app to generate further friends recommendations. It looks like this "Use my contacts" upload your contacts to get more personalised friend recommendations. Unless I am wrong if you select this, whilst not only making friend recommendations, what it also seems to do is also share ALL your existing GC friends and their GC friends details (aka real names) to those who you are connected to in GC. There seems to be no way to turn this off!!!
