Feature Request: Timed / Self-destructing gifs / posts

Hi there,

You've probably heard of this before, but perhaps y'all could consider a self-destructive post function?  So, you can set a toggle and have a post self destruct after # seconds.  This would be intentioned to post a gif for only so long before deletion so repetitive or annoying gifs will remove themselves after the period of time.  I understand that it may tread on the deletion confirmation dialogue box, but perhaps that can be a settings toggle to allow for deletion without a prompt, or to make an exception for timed posts.
