X日後にカテゴリ内のトピックを自動削除しますか？

[JammyDodger]

現時点では既存のツールでこれを自動化することはできないと思いますが、Feature リクエストはオープンになっています。

Category-level auto-delete topics the same as auto-close feature

this is a feature request to make it possible to have a category where users are free to discuss without any concern. two use cases I can think of: for newbies who may be afraid to participate, one can config a category whose topics are temporary and is more like a test environment (like try.discourse.com). for countries with lots of censorship (less freedom of words), it’d be much safer for users to discuss temporarily rather than permanent.
