A profile is being generated about you, slowly but surely. It starts out as a vague picture, but the more you communicate, the the more clearly you define yourself. It includes your political affiliations, interests you display online, who your friends are, your every movement, your sexual preferences, close secrets, and anything else that can be gathered about you. These profiles are stored in a government database…
... And you can't 'escape' it. Eventually a lack of data on you will be suspicious in and of itself.
