is there a tag for a requested drawing by an artist's follower?

See this post: (nsfw) post #9644612

there's a lot of posts where the artist is drawing something in response to a comment by one of their followers. I am not sure if such a tag exists. Not the same as commission tag.

anybody know?

We have request inset, though that’s only when the actual request is visible in the image like in your example.

fan request was (i think) an attempt at creating such a tag, though it's very underused right now.

There's also requestor upload for requests uploaded by the requestor.
