The idea presented in that report is nuts. You have to provide an email, DOB and postcode to get a BBC account but they don’t verify the DOB and postcode is actually yours and unless your email address is all over the internet and associated with your full postal address how are they going to use that?
I *never* give my true date of birth to any web-based service unless it’s absolutely essential and legally necessary. I assume any service is going to be hacked sooner or later and the less they really know about me the better.
