Imo, a good rule of thumb for when you're copy/pasting the same comment you've made before is to mark it somehow, e.g. "as I said the last time this same issue came up (perhaps link to comment here): [paste]".
A bigger question might be why you're saying the same thing over and over to begin with, paraphrasing or not. Is your one-paragraph comment filled with self-help-type platitudes really interesting enough to spam in every relevant discussion?
