Lichess Forum

Hello!
I want to know when does a Lichess topic/forum archive?
~ Is it based on how much time has passed since no one has posted a message or what else??
Please tell...

Moderators can close forums. I think there's no other way.

Moderators can close the topic,or the forum topic archives automatically after 1 month,if nobody replies in them.

Yes that I know, but I want to know the other way if any.
