4chan operates on a strict rotation system. Each board has a limited number of pages. When a user posts a new thread, older threads with no recent activity get pushed down. Eventually, they fall off the last page and are deleted from 4chan’s servers. This process is called "pruning."

Its URL schema is designed to mirror 4chan—one can typically replace boards.4channel.org with warosu.org to view an archived version of a thread.
