Well, you never have absolute security with anything you do on the internet. People mentally weigh the risks and make decisions. Obviously not everyone is tech-savvy, but using a third party snapchat app in the first place is a stupid decision. I don't have to worry about any of my snapchats being released in this leak because I'm not a dumbass, so I really don't pity the people who were dumbasses and do have to worry.
