TAGS "BROTHER" AND "FATHER" ARE FOR INTERACTIONS BETWEEN MALES STRICTLY, AND DEMANDS TAG "YAOI".
For ANY kind of heterosexual incest ONLY FEMALE PARTICIPANTS should be tagged.
...
In plain words:
TAG "MALE:BROTHER" IS ONLY FOR A BROTHER FUCKING A BROTHER WITH NO FEMALES OR DICKGIRLS PRESENT. IT DEMANDS TAG "YAOI". FOR ANY KIND OF A SISTER AND BROTHER FUCKING, SISTER BEING DICKGIRL INCLUDED, ONLY "FEMALE:SISTER" AND "MIXED:INCEST" SHOULD BE TAGGED.
TAG "MALE:FATHER" IS ONLY FOR FATHER AND SON FUCKING WITH NO FEMALES OR DICKGIRLS PRESENT. IT DEMANDS TAG "YAOI". FOR ANY KIND OF A FATHER AND DAUGHTER FUCKING, DAUGHTER BEING DICKGIRL INCLUDED, ONLY "FEMALE:DAUGHTER" AND "MIXED:INCEST" SHOULD BE TAGGED.
TAG "MALE:INCEST" MEANS ONLY MALE RELATIVES ARE FUCKING IN THE SCENE. NO FEMALES OR DICKGIRLS PRESENT. IT DEMANDS TAG "YAOI".
TAG "FEMALE:INCEST" MEANS ONLY FEMALE AND/OR DICKGIRL RELATIVES ARE FUCKING IN THE SCENE. NO MALES PRESENT.
THERE ARE ONLY HETEROSEXUAL INCEST IN THIS COMIC. THIS MEANS - NO "BROTHER", NO "FATHER", NO "MALE:INCEST", NO "FEMALE:INCEST"
Conclusion. Honestly, this mistagging begins to look eerily like deliberate vandalism at the point.
