Precursors
Confession Blogs/Anonymous Confessions
Confession Blogs are a type of single topic blog where people can submit confessions. While some sites require registration, most of these sites operate anonymously. On Tumblr, confession blogs are often populated by anonymous submissions and relegated to a certain topic or fandom.
Origin
The meme, resulting from youtube users combing images from anonymous confession blogs and the Thread Simulator meme, began sometime during 2012, not long after the first non-4chan thread simulators surfaced. One of the first instances of the meme was a video uploaded by youtube user malkouho entitled Dirty Disney Confessions Thread Simulator v 1.0. It would gain nearly 24,000 views and 198 likes over the subsequent two years.
