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
I definitely do not believe any of these stories of comments intentionally restored. Not one piece of concrete proof of it happening has been submitted by anyone. It's definitely one of those "do your own research" things.
But also, Reddit is responsible for this situation by not having a first party tool for self-service full account deletions. They deserve all these conspiracies hitting them for omitting such an essential feature.
