Reality TV
It was interesting to hear about how the secrets of Reality TV get exposed, mostly throw it's own hubris and overwhelming desire to profit from short term fame at every possible level.
It seems that one of the recently finished reality TV shows had exposed the winners name many many weeks ago, long before broadcast had even started. This occurred due to bookings appearing across the country for a speaking/publicity tour. You have no choice now but to use genuine ID, things like drivers license or passport are required for air travel and even for some accommodation. Data mining allows the Internet of Trolls to assemble(dox) potential candidates and the resulting vectors neatly identify the pre-determined results, secrets are secrets no more!
