They get edited back. I've been playing this game for 10 days. I edit once or twice, then delete a few days later, and there's still comments popping back.
the delete event is the trigger thier automation uses, they can't trigger on the edit event as there are too many legit uses of it. However undeleting by default for a time period is easier and will result in less tickets.
The second time I tried, I used a forked PDS that had a 5s timeout modification, edit only, no deletes. It edited my comments, but only up to two months. The rest don't even show on my own profile, but I still find 10 and 11 months old comments if I search online.
I used the 5s delay PDS fork and while it took several hours to overwrite thousands of comments, several days later they all show my protest message, even older ones.
How do you find those unedited comments? Anyway, I ran it overnight and it said to have processed all 2k+ comments and I did check many pages (not all) including the last page which had almost 2y old comments, and all of them were edited. I had to make a second pass only because some subs were closed for the blackout and those comments couldn't be touched
I'm leaving reddit for good, because of how the admins and owners are mistreating third party app developers, mods, and users. I've moved to the Fediverse, which is a much nicer place, made by users and for users. I advise any who read this to do the same.
If I was to try running the tool again, I would pick an unusual word for the edit so I can search my username and that word to see if they hold in time
That doesn't remove your content, it just makes your profile on new reddit blank. You can still see your profile on old reddit if you're logged in (for now).
