The bulk update request #8143 is active.
remove alias art_collab (0) -> collaboration (2)
remove alias art_collaboration (0) -> collaboration (2)
remove alias multi-artist (0) -> collaboration (2)
remove alias multi_artist (0) -> collaboration (2)
remove alias multiple_artists (0) -> collaboration (2)
remove implication multi-animator_project (8) -> collaboration (2)
Reason: Taggers are confusing collaborative tag with collaboration tag.
I submit
1) that the tags are too similar, AND
2) artist collab tag should be artist_collaboration (or something similarly more specific then just collaboration).
Wiki of collaboration: "Images or animations that were created, or worked on, by two or more artists."
470 posts tagged with collaboration, but only have ONE artist tag: https://e621.net/posts?tags=collaboration+arttags%3A1
(75*6 +20 = 470)
example:
post #2805537
tagged with collaboration, but only one artist (shows collaborative_sex).
On 2019-09-18 tags art_collab (alias #34758), art_collaboration (alias #34757), multi-artist (alias #34756), multi_artist (alias #34755), and multiple_artists (alias #34754), were all aliased to collaboration with alias "Reason" fields blank,
and with NO associated forum link in "Forum Post" fields.
(I thought maybe there was no Reason field back then, but an earlier alias [ alias #34753 ] from hours earlier, did have something in its Reason field)
EDIT: The bulk update request #8143 (forum #405309) has been approved by @scaliespe.
