Hi there @psg3196. I'm from the @steemitworldmap curation team. You can't delete a post from the blockchain but you can delete the content. However, it's best not to do that as people can still trace the original post content. You can also always edit the post, as deleting an old post and reposting again is frowned upon by many, especially the curation guilds as it can be seen as milking the rewards pool.

Hope this helps.
