The bulk update request #3863 is active.
create alias dis (0) -> dis_(disambiguation) (0)
change category dis_(disambiguation) (0) -> invalid
Reason: Same problem as Raymond: there is an e621 user named Dis, who tags this on all posts of their OC, getting it mixed up with dis_(darksiders) and more besides.
EDIT: The bulk update request #3863 (forum #353881) has been approved by @gattonero2001.
