Hybris I remember this one time, on TvTropes, when I posted a stock phograph of three random people and claimed they were my cousins and sister, and you used metadata to figure out a general idea of where the photograph was taken and when, and then found the shirts the people were wearing and started narrowing it down, and then stopped because it was getting creepy.
That is one of my early core memories of TvTropes, and is part of why I never post photographs I have taken.
Why-en-tee-kay-tee.
