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
Spot on. Even when they've been caught doing things most people thought was shady (e.g., last year's /r/place manipulation), they tend to not outright deny it, but rather admit it and offer a half-assed explanation and end the conversation at that.
They wouldn't do something that flagrantly disregards EU/CA privacy laws. If they did it, they'd have have a justification they thought would hold up in court. If they had a justification that held up in court, they'd happily plop it in a comment that's pinned with a few dozen rewards and ignore any responses after that.
