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
That's pretty dubious, otherwise why would I get all these replies from 3-7 years ago? Not new replies on dead threads, but the replies were posted that long ago, and I'm being notified about them now as "new" comments. Seems a lot like deleted posts coming back.
Yes, comments are being restored, but what they're saying is it's not something they're doing deliberately. The scripts people were running were basically failing and comments got restored automatically. That message literally encourages you to run them again or try different ones
That doesn't even make sense. How could a script failing to delete a post have this outcome?
If you ran those scripts while subreddits were dark, the script can't see those comments you made in those particular subs, (they're hidden along with the sub) and can't delete them. Then later when the sub comes back to public mode, your comments will appear as well. So comments you thought you wiped were simply hiding.
Just to add, also check the other sections on your comments when deleting (eg: hot/controversial) because sometimes those ones get missed by the scripts as well.
Not to say that's the only thing going on... wouldn't surprise me if they are bringing back some stuff considering their history of shenannigans.
