The women didn’t post anything. They posed for sexy pictures for their boyfriends, then after the relationships ended, the boyfriends got revenge by posting the pictures.
You would think people would have learned by now NOT to pose for "sexy" pictures that involved any degree of nudity.
Still, there is also an added problem that even some women that didn't intentionally pose for pictures ended up having some taken of them when they were unaware that a bf was snapping photos or recording. It's sleazy, but it does happen.
Save the "posing" for husbands, for whom one does have way more, shall we say "control" over and the "penalties" far more serious.
Other solution, skip the posing and just enjoy the relationship.
So perhaps next time these women might actually THINK about what may happen before they pose for racy photos for their “boyfriends?”
