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’s not a bad idea actually. The Powerdelete script I used is based on Javascript and needs to be started manually in the browser window, I’ll just run the script once a day. But maybe someone with more knowledge can come up with a more automated solution. They can’t restore user accounts forever.
