A nude photo-sharing scandal that rocked the Marine Corps earlier in the week is reportedly not an isolated incident.

Male service members from all military branches have been sharing nude photos of women on an anonymous website called Anon-IB, BBC reported Friday.

The servicemen allegedly post photographs of clothed female colleagues and ask anyone on the message board if they have any “wins” – the term used for nude photos, according to BBC.

"Any wright patt wins? I'll start off with some,” one anonymous user posted on the message board, referring to Wright-Patterson Air Force Base in Ohio.

News of the message board comes days after reports that nude photographs were shared on the Facebook page “Marines United," according to a report from the Center for Investigative Reporting.

The report said that more than two dozen active-duty women, officers and enlisted, were identified by their rank, full name and location in the photographs on the Facebook page.

There are still at least a half-dozen similar groups or sites on the internet dedicated to nude photo sharing within the military, marine officials told CBS News.

"The alleged behavior is inconsistent with our values,” Defense Department spokesperson Myles Caggins told the BBC, adding that the department was developing new workplace harassment guidelines.

The Naval Criminal Investigative Service launched an investigation and urges whistleblowers to come forward with information.
