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.
I filed a request for my Reddit data a week ago, so that I could save my account in its current state, before deleting it, and still haven’t received the notification that it’s ready. This process should be automated and not require human intervention, so I’m not sure why it’s taking so long.
