I'm in the middle of a market research survey that's asking me a whole bunch of questions about how much invasion of my privacy I'm willing to tolerate in order to receive more "relevant" adverts. The questions are all multiple choice, as usual, so let me spell it out for them here:
An advert is irrelevant BY DEFINITION. That's why you have to pay money to show it to me.
Are we clear now? Yes? Good.
