Notice the girl in purple (she is fully clothed (no cp)) but she is being used to bate guys into buying memberships thinking maybe she does get naked.
Clearly there is a watermark on the pics "A Little Agency" so you cannot tell me the gallery designer actually believed these pics were just "uploaded by the members and I have no way of knowing that they were 1) copywrited and 2) of a model below the age of 18."
The watermark alone should have stopped you from using them since they were copywritten.
