Update: As some have pointed out: the restores can be rollbacks from the server issues or post haven’t been properly deleted due to subs being private during blackouts. Many have experienced the same issue, I can’t explain how this happens. I’ll just run the script again, try the GDPR request and delete my account.
Also worth noting: according to the ToS Reddit can actually do whatever they want with existing content, apparently we agreed to this when signing up.
That should be the policy but Reddit states it can take up to 90 days to disconnect content from a user profile and personally - I wouldn’t bet on it if it seems they are doing this manually (why else would this take 90 days?).
