If you are interested in deleting a post, the options are limited. Once again, you cannot have the instant gratification of deleting the post from the blockchain on the backend. But you can edit the website frontend page to not have the original text.
A growing trend is to type "Deleted" in the title of the post and replacing the original text of the post body with "Deleted." This removes the original wording from public viewing. Beware if you have unpaid rewards, though, as any downvotes will begin cleaning the post out. Be sure to save your original post text, in the event you want to put it back! The only caveat is that you have only the first 12 hours to edit your post. Once it pays out, it cannot be edited or "deleted"!
