Another topic of intense debate is underage children sharing sexually explicit images with each other. Given the fact that many underage teenagers in the EU and U.S. are sexually active and many possess smartphones, there's been a rampant rise in teens trading sexually explicit video and pictures. According to laws in the U.S. and most of the EU, this is classified as "child pornography". Teens can face prison time, even if they were the same age, were only sharing with their significant other, and were not being malicious.
Making the matter worst, most teenagers are relatively ignorant about the law when it comes to such matters. And enforcement is inconsistent -- 999 out of a 1,000 or even 99,999 out of 100,000 "sexting" incidents go unreported or are dismissed by local law enforcement, but occasionally an unlucky teen actually has been sentenced to prison for such behavior.
