The content indicators branch is intended to be a less geographically specific tool than the 'age rating' used by convention, for warning about things that might cause offense. Obviously there is still a degree of subjectivity involved, but hopefully will prove useful for parents with delicate children, or children with delicate parents.
Is naked human shown? + for an ankle, *** if you glimpse a garter... er... I guess stuff changes with times. Nipples seem to be a particular issue at the moment in certain parts. Anyway, censor with a + for some nude transformation, chuck *+ for shower with omg, nipples, and go all the way to *** for close up gentiles of either gender, even if covered by a jew or pixeled out in a particular release.
Is there sex? If it's offscreen or 'implied' give +, and ascend to outright pron at ***.
Is violence prevalent? For just a bit of slapstick throw a +, for poping eyeballs and close up disembowelment bestow ***.
Do you think your Mom's a hot bitch? Or how bout your Sis? We don't wanna know, however, if a character in an anime thinks like that more often than in 1 ep, then you could add a +, if the character does more with his/her family member(s) than wash their back, then it'd probably be best to warn (or tell them the good news) and give it ***. Although we all know that incest in anime is a big lie and they're NEVER blood related... Kaze no Koi isn't incest, it's uh... well... ^_^;
