There should be a way of flagging comments on pictures as well as pictures themselves... This is one of my biggest pet peeves here. It's no wonder women have their guards up here. So many sexual comments.Remember they have to be your friend to be able to post comments about your photos and some people are interested in collecting friends with one case over 11,000 friends and others with 5,000+ friends.
It's still not appropriate. I've seen people write comments about another's slit, wanting to eat out of their ass, amongst other things. Even if this doesn't make the one person uncomfortable, I know it makes others uncomfortable. And nudism is about being comfortable.
