When getting car/home insurance quotes, you have to enter a lot of personal information. Most of the information is relevant to the quote, but personal details like your name, contact details and exact address (rather than just postcode) usually aren't. They don't need to email me the quote - I'm happy to just see it on screen and perhaps download it - but of course they want my contact details for profiling and data mining. I'd prefer to only give these details to the company I decide to purchase from, not all the others.
In the past I used false names and throwaway email addresses, but now they seem to recognise that and tell me (after filling in the whole form) that they can't give me a quote.
Does this bother you too? I feel it should be a legal right to get a quote with only the minimum data required.
