I don't think there is such a thing as "a  little bit of nudity" when it comes to the censor options. 

I too don't mind a little bit of nudity so I don't turn on the nudity filter.  However, today I went to check out the gallery since the changes and in the first page of 18  thumbnails there was a close up of a woman's butt, 2 close ups  of a woman's pubic area (one was quite suggestive), an S&M image and various naked boobs. 

There was also a cute faery/angel image that was tagged "nudity", but there wasn't any nudity in the image.  If I had the nudity filter on I'd have missed that image, which I liked enough to leave a comment.

Instead of nudity filters, they should have a 'ratings' filter.  Anything nude or violent is "R" rated, while scantly clad but no nudity could be "PG", anything else "General".  That way you can filter out based on rating and have more of a choice.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
