I made my thoughts on necroposting known here:
It was never explicitly stated in the rules, because it doesnât make sense to apply a blanket ban on necroposting in all cases. If the topic calls for it, fine. But if the user asked a question, and received an answer, itâs not fine to suddenly bring back the topic. If the user is annoyed by necroposting, itâs not fine to necropost in their threads. If you donât know whether the user would appreciate necroposting, itâs better not to do it. If youâre necroposting and going off-topic at the same time, especially on serious topics, that is absolutely not fine.
