Well I understood that rule, it's rather the term 'sex-appeal' that leaves a lot room for interpretation and that is likely the reason for a lot of unwanted posts but also unwanted deletions.
Got a Katherine Heigl picture out of one of the deleted post and while it surely is no grade A picture on the Sex-Scale, having a good look on her Bikini Top is surely enough to cover the term 'sex-appeal', it was also no bad, low-res, double, fake, or any other crap.
Anyhow I glad that the rules about the more liberal because nude only would likely mean 80% of the picture threads could be deleted right away because a lot is sexy but simply not nude.
Sorry if that raised your workload.
