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.
Yes it is, as pointed out here https://kbin.social/m/RedditMigration/t/34112/Updated-Reddit-is-quietly-restoring-deleted-AND-overwritten-posts-and#entry-comment-140833 and here https://kbin.social/m/RedditMigration/t/34112/Updated-Reddit-is-quietly-restoring-deleted-AND-overwritten-posts-and#entry-comment-141285
