As a PSA, remember that the API changes don’t only impact third party apps & accessibility tools, but also your ability to bulk delete or modify your Reddit history. If you intend to delete or modify your previous Reddit posts, be sure to run a tool like Power Delete Suite today before the shut down.
Also remember that as Subreddits went from private to public, there may have been posts and comments you attempted to delete but couldn’t until they went public again. So if you ran these tools, you might want to run it again to make sure you got everything.
Irritating people looking for answers is part of the point of the deletion. They can and will find answers somewhere else, and if they keep finding blanks on Reddit, they will start ignoring Reddit search results. That is what will hurt Reddit, not just having less data to sell through the API. … and don’t worry, everything on Reddit is backed up somewhere else anyway, if you are desperate for a specific post or comment.
