As I have maintained all along...
(Tin foil hat on and special flamebait shirt done up!)
Most people use those bloody insidious supermarket loyalty cards, which in my opinion are the biggest excuse for a private company to gather personal information. TESCO, whom I believe have one of the largest customer spending habit databases in the country, but no one minds using the cards and getting their tiny little prize of a fiver off their shopping, at the end of the year do they? Before you start bleating about Phorm/BT, double check your wallet and make sure your shredding your waste paper too!
Until Joe Public actually hears anything about this, this is simply going to be a big shouting match in a quiet little geek corner. Want to make a difference? Simply tell everyone you know who is on the internet in some form or other, that basically their credit info and personal details will sold off to some ad agency in about 6 months time, unless they kick BT/VM/TT up the arse to demand Phorm be removed ASAP. Oh and ask people to stop using those nasty little loyalty cards while you're at it!
