I have acquaintances like that as well. They are usually the "I have nothing to hide" kind of type. :(

An easy disarm is "You are confusing privacy with secrecy. It is no secret what happens in the bathroom. It doesn't mean we are going to remove the doors because people still want privacy"

The bigger problem for me is how facebook tracks and identifies even people who do not have a facebook account. They simply infer such a person exists from photograps, contacts and other one sided activity and can start to track that person, tie all this information together and then target them with ads even though they never signed up for Facebook. Such shadow profiles are a much larger problem to me than people wh…

One way hashed (that can't be rainbow tabled) are not however PII afaik however, so it's quite easy to turn an IP address into a "net location ID" or something similar that can't be tracked back to a physical IP for analytics.
