I came across today one of my own comments on Reddit with a search on duckduckgo. It was still intact. The problem is I used shreddit to randomise and delete the entire contents of my account. My account comments and posts all show empty on my account pages on reddit so there should be nothing.
I did a site:reddit.com search using my username and found ~50 comments that Reddit has undeleted but also hide from my own account. I could still edit and delete them. Its curious that they don’t appear on my accounts content on Reddit and yet a search engine can find them and they are still served by Reddit. Ex Reddit users who deleted their account contents should be aware this is happening and report it as a GDPR breach to their respective agencies if they are in the EU if they too find this has occurred.
Several of us have noticed this since the protests and mass exodus started. It did seem that editing then deleting might protect against Reddit’s restoration of posts and comments.
Update: Just checked. They’ve restored a lot of my old posts. This may turn into a years-long game of whack-a-mole trying to actually get our material deleted from that site.
