Or you accept the fact that what you write is a permanent record. (Local admins can delete messages from their servers if there is a problem with the content.)
That being said, there are Control messages (RFC 5536 § 3.2.3), and one of the things that they can do is cancel an article (RFC 5537 § 5.3). You'd probably want to authenticate the cancel messages of course:

Worth noting that you can't force servers to honour the cancel messages and delete the article on their local storage.
