What about offline tracking? I went to a big box store today, and after I got home, I got an email asking me to review my visit. Now, I'm sure that somewhere I ostensibly consented to any and every form of tracking, but it was startling to have my nose rubbed in the fact that every time I use my credit card and everywhere I carry my phone it is being tracked and linked to every available piece of information about me, which I'm sure is far more than I would like to be public.

I don't fill out surveys anyway, but I was feeling particularly pissed, just because it should be socially unacceptable to behave like this, just because you think you can legally do it and nobody can stop you. So I flagged it as spam.

Oh, and the chain store that did this has been in the news for data breaches, not long ago at all.
