Snapchat has an important message for its young users: “keep your clothes on!” 53% of 13-17-year-olds use Snapchat, according to Ypulse’s most recent social media tracker survey, and the app has long battled a reputation as a sexting haven. New community guidelines recently posted by the app are serving as a gentle, but stern reminder for minors to “Keep it legal.” Team Snapchat is trying to pull in the reigns on inappropriate sharing, threats, bullying, and invasions of privacy, and violating the rules could result in content removal, suspension, or being banned from the app. (New York Daily News, Snapchat)
