Fan art deletion needed

In the past, I've managed to delete fan art by a guy named Dave Dunlap from some Batman/Batgirl titles. I thought that was that, but now I saw this picture on a totally different kind of tv series: https://www.imdb.com/title/tt0066636/mediaviewer/rm1707629569/

Therefore I'd like to ask if a staffer can check if this person added more fan art to other titles and delete everything please? Also, can a message be sent to this person to point out that fan art is not allowed?
