30 day post limit

This idea has its drawbacks, but I feel like this is necessary now that gravedigging is out of control. In Fandom, most forums don’t allow anymore posting after a discussion has been inactive for 30 days. Perhaps the creator of the discussion could be allowed to revive it, or mods, but this is getting pretty ridiculous. A lot of new members don’t check the time and some people just don’t listen no matter how many times you say it to them… that trying to “answer” months-old questions or making comments don’t help anyone. Is it possible to create a similar, automatic solution, or is all this just controlled by vanilla forums?
