Should the users or hackers be blamed for the leaking of pictures on Snapchat?

Snapchat is an app on which a user can send pictures to other users for a limited amount of time before they disappear forever... or so they think. The article on BBC titled "Nude 'Snapchat images' put online by hackers" by Dave Lee explores the recent situation of pictures, many of which are nude, from the app snapchat being leaked by third party apps. The article takes the right stand in explaining that the users who's images were leaked were victimized by the hackers, and that it was a violation of their privacy. Another stand that the article could have taken was to say that it was was the user's fault for sending the nude pictures in the first place. However, according to the guidelines of snapchat and the privacy the app promises, users should be able to send what they want with a reasonable amount of confidence that they will not be leaked. The victims of violated privacy should not be blamed for acting the way that they did in the first place, because it was their choice.
