I think I'll create a consolidated thread for these.

Newest one: tachibana_tomoe_(artist)

I'd still think that all the banned artists should have an implication to a banned_artist or similar tag for people who upload their work here and don't know about the removal request.

I can't find k96's name/URL in Artist: banned artists. (forum #46383)
Should I edit Artist: banned artists and Howto:upload?

Newest one is juuhanna.

akashirokai is banned.

kyara36 is banned.

melting scarlet is banned.

Albert recently purged all of kumaori jun's works. I've updated the banned artist list and the artist's wiki.
