"After all O2 provide home broadband don't they ? Are you suggesting that just because O2 handle mobile traffic that their home broadband should be proof of age too ?"
You aren't allowed to get home broadband and sign into a contract unless you are over 18! That is surely proof enough? The argument could be made for contract pay monthly mobile phone's where you still have to provide proof of age to surf the pr0nz, BUT mummy and or Daddy can be talked into getting a jebusphone for the sprogs on a contract so they don't get picked on at school and can then in turn ring mummy or daddy when they are being picked on without fear of them running out of credit, thus the age check is still necessary!
The point is if this is going to blanket the UK O2 could find themselves in a sticky situation when someone complains that there 13 year old off spring has been watching pr0n on O2's free wifi that they have been filtering out at home!
This is line gives you the reason for that concern.. "When you first connect to the O2 Wi-Fi network, you'll be presented with a request for your name and mobile number."
So registration without address, age, proof of age, biometrics, NHS no, bra size, shoe size, mothers maiden name, inside leg measurement is an option! Thus a free internet for all regardless of age and content genre, i'm all for free internet's, i am all for open content genre, i am not all for kids looking at pr0nz, not many people are, that's why its illegal!
O2, please think of the children!
