Allow the editing of name with guest posts

If you allow guest posts and have them moderated. I see you can edit the text message they wrote to remove any offending stuff before moderating it. But notice you cannot edit the name a guest picks. The option to be able to edit the name a guest picks should be added because from my experience when you allow guest posts and they can pick a name, they will use offensive names at times, or try to pose as somebody else, etc. And if you cannot edit the name out from guest posts during moderation - then that means you have no option but to reject any guest posts that uses an offensive name, even if the post content was perfectly fine.
