The content of this tweet demonstrates that the artist who posted this photo in the source tweet was not the one who took the photo, their work is post #3024785.
That in mind, I think this image should not have an artist tag unless we plan on uploading more of the photographer's work.
When I uploaded this originally I tagged it with an artist_request as a joke since it's patently absurd that a photo would have an illustrator. This was a mistake. I've failed once trying to remove the artist tag and I don't want a back and forth so I won't be trying again, I just want the point made clear.
Most photos containing real people aren't tagged real life unless it's a well-known person who has a character tag. The point of real life is to have an umbrella tag for real people like those listed in tag group:people, who have a character tag but otherwise don't have a copyright tag.
