Can you disable that?
IMHO, it hinders discussions, because even old topics can often be useful/discussed after a longer time in the future.
There is a thread about this where you can see the reasoning from the powers that be: Auto closing topics
(Ironically, it has closed already.)
FWIW, I agree with you. It feels like trying to solve a problem before you know that the problem actually exists.
We don’t pay a “new topic charge”. If you want to discuss something again, assuming you want to add new information and not just renegotiate something that was closed, open a new topic and link to the closed discussion.
Having said that: we explained our reasons for keeping the automatic deadline from the last reply.
