How do you respond after the response (a nice and polite response)

More than once, people make mistakes in the format of the thread, which of course makes it difficult to read (and even more difficult for the media themselves) and is also annoying to the eye, as you ask and ask again and again.
Maybe it’s worth posting a short, simple explanation somewhere on how to respond to a thread (or pop up a small notification if the same username responds again in the same thread). Of course, if there’s a way to duplicate the response button from the first response to others, that’s better.
