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.
Probably better to replace your comments with some gibberish generated by chatgtp instead of deleting them. It will be much harder to figure out on mass scale if the edit was legit or not compared to them just looking for recently deleted comments or comments that mention something like “comment deleted by x tool”.
