The general consensus seems to be that sexting is the primary use for Snapchat, an app that sends and then destroys selfies - usually nudes or scantily dressed ones.
This could be because the above original screenshots in the Snapchat App Store were of pretty girls in bikinis, and users of the app were warned of “Mature/Suggestive Themes” and “Infrequent/Mild Sexual Content or Nudity.”
Evan Spiegel, the founder of Snapchat admitted the mix-up in 2012 saying;
“To be fair, our early marketing materials were a bit amateurish. I took those photos on the beach with friends. They were fun and playful at the time, but didn’t represent how the app was actually being used.”
Now, the models of those pictures are taking him to court for big bucks!
