I did one the other day that showed a nipple and didn't realize if. I didn't even notice because I was more focused on her butt. One of the flippers, someone I hadn't heard of, pointed it out. I was a good boy, flagged it, and much later that day, it was marked accordingly.
I know, it'll take me forever to hit a million points if I keep up the NSFW posts, but they're fun, and that's what I thought the place was for.
