The action of locating and reviewing content previously removed from the Reddit platform is the focus. This includes posts and comments that have been deleted either by the original author, a moderator, or Reddit administrators. As an example, one might try to recover information from a discussion thread that has since been taken down.
Accessing such material can be valuable for research, historical analysis of online communities, or simply for personal reasons such as retrieving lost information. Understanding how communities evolve and change over time often necessitates the ability to view past conversations, even those that are no longer readily accessible. The process itself has become more common as online archiving and data preservation has become more ubiquitous.
