ZahrGnosis writes "Through work, and bad planning, I've been subscribed to a lot of trade magazines. I don't generally hate them, most come electronically now, and some are actually useful. What I despise is the annual calls to renew my "free" subscription and update my info. Ok, giving away my work e-mail, title, and line of business info isn't that bad, it's practically good marketing. But at the end of each call the phone people say "in order to verify that we talked to you, can you tell us" followed by something tiny and seemingly innocuous. The last digit of the month you were born in, or the first letter of the city you were born in. Today it was the country you were born in. I've started lying, of course, because noone needs to aggregate that sort of personal information byte-by-byte, but now I'm convinced that's what they're doing. Does anyone have any details on this? Can someone confirm or deny that these seemingly innocuous "security" questions are being aggregated. Yes, I tried some google searches, but my fu seems weak in this area... or noone is talking about it yet. Bueller?"
