Got some DMs about this so I guess I'll make a topic about it.
A while back I removed Cernunnos from a bunch of Baobhan Sith (Swimsuit Pretender) (First Ascension) posts. My logic is (I think) pretty simple: if the only presence of Cernunnos in the post is her character hat, this is basically redundant with the already existing costume tag and pollutes the Cernunnos tag. This is in-line with my other gardening of Xu Fu to replace many instances of Yu Mei-ren with Lady Yu doll, and my addition of the clause about the Xiang Yu character hair ornament on Yu Mei-Ren (Swimsuit Lancer)'s wiki page.
I will admit I failed to add any such clause to Cerpriestess' wiki page, and will do so if the fact that I did this to begin with isn't extremely controversial and reversed.
For reference, Cernunnos currently has 582 posts, a lot of which are already character dolls/accessories on Baobhan Sith posts. Baobhan Sith (Swimsuit Pretender) (First Ascension) has 644 posts (570 of which don't have Cernunnos already tagged). Adding the Cernunnos tag to every Cerpriestess post would basically just result in the Cernunnos tag mostly being a Baobhan Sith with a fluffy white hat tag.
