I cleaned comments of 2nd one (useless for the site)
I guess that for the first one it should be pixelated then, though that it can hardly be considered as pornographic.
Americans are too prude

The message I got from Google was super vague, didn't include precise examples, and included these case examples :
- Pornography
-> full nudity scenes
-> pornographic images, videos or games
-> pornographic anime or cartoons
- Sexual contents
-> concealed nudity
-> transparent clothes
-> obscene or provocative posture
-> focused on breasts, bottoms or genitals
(rough translation, I got all that in French)

And no guarantee that removing some (or even all) will solve anything, since I do not know which page is concerned!
