Social media and interactive sites move fast, with "friends" and contacts posting photos of themselves in often provocative poses and outfits. Teens are often caught up in this trend and might feel pressured to post comments or pictures of themselves to compete or feel good about themselves. This includes highly sexual images, statuses about risky behavior and comments that may be crude and offensive. Susceptible teenagers may not realize the loss of privacy and their reputation until it is too late. Images of teens can easily be stolen and posted elsewhere. Teens that don't fit the mold or follow trends may be bullied online by others. Cyberbullying is now the most common type of bullying and involves taunts and threat via social media, email, texting and forums. Cyberbullying can sometimes lead to mental health problems, self-harm and suicide, notes CommonSenseMedia.
