I’m not sure if it’s a coincidence, but I raised a case with the ICO in the UK, and today they got back to me asking for all my communication with Reddit. Also today - after a month of silence - Reddit also emailed me with this
If you’re in the UK and had been affected by posts being restored, I’d recommend contacting the ICO. It takes less than 5 minutes
Shit database replication would also do it.
They probably never even tested for mass deletion events and probably still don’t.
While I am unsure if it’s malicious I would not be terrible surprised to find out it’s just a case of bad assumption in system design or bad code.
