What is interesting is that reddit claimed they couldn't show mods deleted comments for "lawyercat" reasons[1]. Mods used to be able to check deleted comments for harassment via Pushshift. Has the legal calculus changed so much in the past month that reviving comments to the general public is now okay?
I don't see how GDPR can't force them to remove all comments? Additionally, there is no reason Europeans can't own multiple accounts and that accounts can't change hands. So a single European should be able to delete thousands of accounts?
Reddit will anonymize -- well, "anonymize" -- the data by disassociating posts and comments from the username. This is potentially gdpr compliant (anonymity is a valid way to do things!). There's separately a balancing act: eg a post is valuable to everyone who commented in the thread.
So it's not clear that this is wrong, and forcing them to go further will be a slow process involving complaining to a country-specific DPA; getting that DPA to take on what will be a very low-priority case; letting the DPA process play out; and seeing if Reddit will appeal.
