Can I post nude pictures in my threads?
If the picture is of a REAL PERSON and is pornography NO. Not even under spoilers.
If the picture is ART, does not show any private parts or inappropriate content, yes.
If the picture is ART, has visible private bits, Yes and must but put under spoiler tags.
***A GOOD RULE OF THUMB: Would someone get in trouble if they were caught looking at that picture during School or Work? If the answer is YES - put it under a spoiler tag.
