How do I make posts in a certain category ephemeral?

[blue-cat]

I want posts in a certain category to be deleted after a period of time such as one year.

Can I do it with nodebb?

Not avaiable out of the box, but you can use something like https://github.com/julianlam/nodebb-plugin-archiver or modify it to delete the topics instead of locking.
