The artist bikusen (artist #31409 ) is listed on it's Wiki as being banned, and their URL (http://www.pixiv.net/member.php?id=9376) also appears as one of the URLs of the Banned Artist listing (artist #42344), however the status of the artist is still "Active" and not "Banned".
Edit:
I see it's changed. Thanks.
