I had a total of 4 advertisers remaining on mine (if anything I'm doing better than most). Audi, a local real estate group, a betting agency, and an airline/frequent-flyer account. Obviously I don't want and didn't volunteer my details used for use by any of these for advertising or tracking purposes. The frequent flyer group have just taken it from my membership details. I don't bet, but I've worked as a statistician, so there's probably some connection there with past probability and modelling work or getting odds from these sites. The real estate group I'm guessing is from contact details given while looking for houses that they've used without my explicit permission. Audi is interesting because I've never had a car in my name, and haven't had one in my household for several years. Haven't so much as stepped in a car dealership. I'm guessing they must have bought(stole?) it from a rental or car-share company database...or a marketing list somewhere, but its certainly not from anything I've done first hand.
