You never ever ever for any reason delete a post. Unlist it but don't delete it. If anything ever comes up in the future about a previous post and you need to defend yourself? You're screwed. If it's Unlisted, you still have it but no one sees it but you.

Same with "poorly written" articles. One, why would you even publish garbage? Two, rewrite it, use new images with citations, and rewrite the title. Unlist the original and post the cleaned up newer version.
