Updated: Reddit is quietly restoring deleted AND overwritten posts and comments

Another update and possibly a solution for some case where posts were not properly deleted. Seems I jumped the gun on this and the restores haven't been intentional - at least not in this particular case.
There is a limitation in the popular Powerdelete that apparently prevents mass editing. Here is a link to a new version with a build-in delay and some other alternatives:

There are other reported cases where manually deleted post reappeared or other scripts have been used, so this doesn't solve all issues but explains how posts that were both edited and deleted withPowerdelete weren't properly deleted and reappeared after subs went back live.
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 link is just too request the bulk of your data. It's not a form to request deletion of all your data. Technically you could request that, but if they deny out ignore that, then there's not a whole lot you can do unless you're ready to take it to court.
If you're in the EU, report it to the Data Protection Authority in your country. They must provide you with a copy of your data and also purge it upon request.
The EU or the UK. The Information Commissioners Office would take an exceptionally dim view of this shit.
I'm not sure whether under GDPR your posts would be classified as Personal Identifiable Information - which is what the GDPR is mainly about
