General Discussion

How on earth can a survey be valid when there are no control mechanisms in place to ensure that those 'voting' do so only the once?

Yes and just think, all those who have given Tesco valid names, addresses, tel nos and e-mail addresses, of all that personal data about you that Tesco now holds.

To be honest i would rather give Tesco's my personal details, at least i know they would be safe. I had a letter last week informing me that all my personal details including bank account were on the discs that the bloody government lost. Checked my account today and i don't know if the wife has been christmas shopping or if some theiving twat has nicked my money!
