Bending the rules?

I have read the rules of the website over and over, and I'm grateful for no porn. but I ran into the tag, "topless" the other day. I know the rule of no nudity, but isn't it pushing this sites rules a bit? I do enjoy this site, but why does the tag exist and the pictures on the website?

I would like to hear peoples opinions on this whether you usually post or not.

nude is also a tag.

Recent posts aside topless/nude have historically been closer to post #311320 where she's not wearing a top but there's no explicit nudity.
