it seems that the fucking morons that run reddit have decided to mess with people’s messages now, basically any conversation started before 2023 is now gone. However, there’s a small chance to recover them, as per some admin:
you can request the data export from Reddit at https://www.reddit.com/settings/data-request and this data should contain all chats messages from all chats
looks like that pigboy u/spez is really set on destroying reddit. gg.
