How is this going? I started getting serious about this today, and so far it’s just been a real exercise in frustration. It seems if you have too many comments, Reddit hides the really old ones, making them quite difficult to locate.
@earthling is having the same issue. What are you using to access reddit?
I modified the script from https://kbin.social/m/RedditMigration/t/16226/Wrote-a-script-to-edit-all-my-posts which uses the python library PRAW. Someone else pointed me to a script in python that’s already using Pushshift though - I am gong to take a look since AFAICT that is the only way to get this accomplished.

I feel like the only way to get everything is to use GDPR archive files. Your reddit profile doesn’t show all of your comments.
Shreddit can use these files, however you have to pay $15 for the feature.
