I made a GDPR request through reddithelp.com last night; maybe I shouldn't have bothered! Assuming I don't hear back, I'll resend the request via email then report them to the Information Commissioner (UK gov dept) if I've had no proper response.

By the way, I'm not sure if the California law is the same, but with a GDPR "right to be forgotten" request, the organisation must delete your data from their backups (or at least make sure your data will not be restored from a backup). Asking you to delete your own comments clearly won't meet that requirement.

Love the guitar solo on this one. Just noticed the new album is out today!

It seems that there's an issue where Reddit rate-limits the comment editing, so many comments don't get edited. There are other versions of the script which add a 5 second delay to avoid getting limited.
