In my opinion, they should get rid of the necroposting rule and instead make it so that once a thread is over a month old, it gets permanently removed from the trending threads and latest threads tabs. This way, new replies on threads that are over a month old couldn’t potentially revive a thread, but the thread owners or people being replied to would still receive notifications and be able to respond.
To be honest, I don’t really see the harm in someone trying to revive an old thread. Unless they are persistently trying to get other people to react or respond to a dead discussion, I think it is reasonable for someone to want to continue an old thread. I haven’t been here the longest, but I’ve never been a part of any community where necroposting has became an issue, so maybe I just don’t understand the problem here.
