Hot on the heels of LCS (https://lemmy.world/post/557346), I bring you Lemmy Post Purger (LPP).
Instances can grow fast, and that can be a problem if you have limited disk space. If you don’t mind losing history that your users have not interacted with, LPP can help. It will purge posts along with their comments and media before a certain time period if no comments, likes, or saves exist for users on your instance.
I feel like this ruins the aspect of an archive of information where users can go back through and find useful info similar to SO in a way. Maybe there will be a meta search engine for looking through all of the popular instances?
