I spotted (and corrected) another wrong artist name:
towaru ana -> kishiri toworu
I guess someone got that from the blog title "Toworu no Ana".
The name can be found on the gallery page or Pixiv, if you want to check it... and there are no kanji to argue over this tine. :P
Anyway, the system was quite happy to let me wreak havoc with the artist information, but I can't change the tag. I assume it doesn't let just anybody mess with these things. Or I'm doing it wrong, of course. Can someone help me out, please?
