The lack of copyright consistency also affects Hasshaku-sama, who still inconsistently gets tagged with either original or 2channel (the site she was originally posted on).
Interestingly, urban legend has been used as a kind of pseudo-copytag for these characters for a while - presumably because the name is too generic to be considered a copyright. We already give some uncopyrightable folklore characters umbrella tags, such as creepypasta and Japanese mythology, so it feels like it would make sense to group these as well.
I think with Hasshaku-sama, the best we could do copytag-wise is just make a tag for her and the other creations of the "Let's gather up seriously, deadly scary stories, shall we? (死ぬ程洒落にならない怖い話を集めてみない?)" thread/topic of 2channel's Occult Board. The thread often gets shortened to '洒落怖', which English Pixpedia translates as Sharekowa (and if not that, we could do one for the occult board as a whole - オカルト超常現象; or OkaBoard/オカ板 for short - since 2channel (/livejupiter/) exists). Kisaragi Station, Saruyume, and Kankandara are also from there, and Kune-kune is believed to be from there too, so at minimum it wouldn't just be a tag for Hasshaku-sama.

(Though as a side note - Kuchisake-onna needs to be sorted out, too. Currently it's getting used as both a character tag and a monster girl tag.)
No idea how to deal with that though.
