With respect, cubflyer, and putting aside the issue of G-INFO for a moment, I think you dismissed Whirly's concerns rather too flippantly. It is easy for us big, hairy-ar$ed males to overlook quite how vulnerable single females can feel about their privacy.
I was reminded of this recently when Mrs Big Hilly (a young, blonde female) went to our local video rental shop (the big high street chain) to hire a DVD. When you hand over your membership card they ask you to "confirm your name and address", which she duly did, got the DVD and drove home. About an hour later, there was a knock on the door and there was a man who had been standing next to her in the queue at the video shop who announced “all right, darlin’, do you fancy goin out for a drink wiv me?” Clearly, he had overheard her giving out her address and decided that he’d try his chances. Luckily, I was home and so came to the door when she called me BUT, it could have been a whole lot worse. . . . .
