Replying to old threads is so unwanted, it has an ugly name: &quot;necroposting&quot;. It&#x27;s such a nuisance that every viable online forum has configuration to prevent it.<p>When any thread can be resurrected, it&#x27;s like a Hydra that can grow a new head out of its ass, not just recently chopped neck!<p>:)<p>Trolls and spammers love to necropost. Trolls do it to annoy. Spammers do it because they are finding postings automatically based on keywords, and don&#x27;t care about the date of what they are following up.<p>The quality of necro-postings is almost invariably very, very low.<p>Even when it is done honestly by a non-trolling user, someone who replies without looking at the date of what they are replying to demonstrates low intelligence, which raises the probability that they are going to post something of low quality.
