Reddit recently removed years of chat and message archives from users’ accounts without warning as part of an infrastructure upgrade. Many Redditors were upset to discover that their chat histories from before January 2023 were no longer accessible. Reddit claims they only migrated data from 2023 forward during the transition to the new chat infrastructure. Some users were able to retrieve some of their old messages by requesting their Reddit data, though others reported that not all messages were recovered. Along with this change, Reddit has recently made other unpopular decisions like ending Reddit Gold, showing a lack of communication and consideration for users’ sentimental attachment to their online data.
Deletion of personal data without consent or lawful base is also a violation of the GDPR.
They probably still have it. I did a gdpr request then overwrote and deleted all my posts. Then deleted my 11 year account. A couple of weeks later I got the request contents, which contained every post, every comment and every DM I ever made. Reddit does not delete when it’s supposed to.
