Power Delete Suite is still limited by reddit. I ran it and it got a lot of stuff, however I was still finding comments older than a few months with 50 or less karma that it missed.

The issue isn't with PDS, though, it's with how many comments reddit will show you. When I go into my profile there are no comments, however there are still some out there.

I'm wondering if anyone has made a script that will edit + delete comments based on the csv files from a GDPR request? That actually gives a comprehensive list of comments (with links) with which to work from, better than the user account page.
