Sex chat and photo sharing
Marines stalked the women on social media and egged each other on to find and share photos, some taken in locker rooms and showers when the women were not aware, others shared by former boyfriends.The story was broken by Thomas Brennan of The War Horse.
One user, for example, wrote: ' woke up horny as hell!!!!!
Girls who wanna play post a comment and I'll kik you'.
There are also thousands of comments on the pornographic images from fellow users urging one another to add more and more raunchy photos or inviting them on to other social networking sites to message privately.
Members are luring strangers for sex by asking them to join in 'Kiksex' on the messaging app Kik, where users exchange rude photos.
It has a military chat room in which members of other services have been sharing such photos. He said the Marines have set up a task force to investigate the matter, following on the Naval Criminal Investigative Service opening a criminal investigation.
