This is clearly an issue of concern. However, just because a photo turns up on
a porn site does not by itself mean it is a fake photo. After all, the photo is
(almost always) a photo of *somebody*. The question remains valid whether the
profile "represents the user", or not, and this (latter) case is described
within our standard set of rules as unacceptable.
You are welcome to raise this, and other issues with the moderators and or the
admin (as you just have), or in the Feedback group, and we will consider each
issue on it's merit.
