Publically posting private sexual/nude media of another person is illegal pretty much universally, with both criminal and civil penalties. Along with laws regarding disclosing intimate images(typically a misdemeanor/delict), posting of these photographs could also constitute as revenge porn. This would make it sexual abuse, a felony/crime.

So, to paraphrase your initial response, unless the victims are willing to commit crimes and provide you with naked pictures of Iskall, they can not be, and should not be, believed.

To get ahead of a BS response you might have to this, true, you did not explicitly ask that the photos be disclosed, but you did say words were not enough. Since words and pictures are all that are known to exist, you inferred that you need the pictures of Iskall to be satisfied.
