I have been looking around and can't seem to find anything on the matter. I was wondering if maybe someone here could give some insight. I am looking for a way (preferably a plugin) to cause posts to become 404 after they have been posted to my blog without having to change the title manually. I was hoping to do this automatically after the post has been posted for a certain time. This is all in Wordpress of course. So for example. at 5pm the blog post goes live. At 5:30pm plugin kicks in, changes post url automatically and now the post is a 404 redirect error/ the page is non existent. Any insight on this subject would be amazing, thank you!
