After the blackout I deleted all my posts and comments on reddit using the PowerDeleteSuite, and since then I’ve come back weekly to find comments existing on my account. I’ve been deleting them by hand now that the API is unusable. Does reddit pull these out of a backup? Do I just now see all of my comments? What’s the reason these comments keep showing up?
It applies to everything you post. The GDPR is supposed to level the power between you and organisations like Reddit. It give you the power to know what data they have on you, correct and delete it. If they don’t let you have this power, you can file a complaint with you data protection office. It doesn’t have to be a formal complaint. Just write them a mail with your problem.
