We know that platforms have made inappropriate judgements in this area, particularly in regards to artistic works, and there appears to be implicit conflations here.
Also, in quite a few cases, someone might insinuate one thing, then another might be represented.
For now, SFW / NSFW should suffice, to explain that:
"sexy" doesn't necessarily mean NSFW.
Some degree of "nudity" isn't necessarily that strange to see either, particularly in a cartoon style, unless someone is prudish to a degree I'm not sure exists. At the very least, that is silly to censor.
