There isn't

If you're talking about your status:pending posts, they'll turn status:deleted if no one approves them after three days.
If you're talking about permanently deleting posts from the site, that's something that rarely happens and only admins can do.
If you're talking about banning non rule breaking posts, then the artist has to submit a DMCA request.
But I guess you're talking about banning post #6605767? It looks like a paid reward. Approvers and above can ban paid rewards.
Could make it so you can only delete (like expunge) your own post within X minutes/hours of uploading it; the media asset would still be available (for now), of course. That way you'd have a small window to undo mistakes, for cases where the site doesn't prevent you from making a mistake. So long as that isn't abused.
