Instances of kids abusing technology abound -- but in one case, when kids use a certain technology as its intended, danger still lurks big-time. Snap Chat is a smartphone app that allows users to send photos and videos that the app promises "disappear within seconds." Sounds fun and harmless in theory, but naturally kids are using the app to send the sort of (often sexually explicit) things they probably wouldn't if they thought the pictures and clips would live somewhere forever, according to KCAU-TV. The problem is, not only can the recipients can grab screen shots they're free to keep, experts who call the app "dangerous" point out that there are servers managing those images, so there's really no telling where they might end up. Because it's illegal for minors to send sexually explicit images, the FBI searches the database constantly for offenders. With more than 30 million images processed a day, this is one app you might want to ban.
