Last night, I used Redact to delete all my comments, then altered the settings to make an exception for one and only one subreddit. To check if I even had comments left in that subreddit, I kept an eye on my comments through Infinity. At first the comments were being deleted one by one, then suddenly it showed a “No comments found” screen half-way through the deletion. So I looked through a post in that subreddit where I entered a discussion, and it turns out that my comments there were still up, despite my comments tab showing nothing. I then checked RiF and it didn’t show my comments through my profile. Today (after having deleted everything), I checked through my comments in my post in another subreddit, and it turns out they were still up, despite the fact that I didn’t make exceptions for it. Still found no comments through my profile.
Yes, since even on the website on mobile or desktop, you have the 1000 indexing limit. PDS relies on hitting the delete button on each comment/post that’s visible. So if you can’t see a comment because it’s past the 1k limit, then PDS can’t see it either and can’t delete it.
Now, the changes to the API probably won’t. Power Delete Suite is a javascript plugin on the browser and when I look at it, there’s no api calls. Rather it just simulates you clicking manually on the edit / delete button of each submission / post.
However, PDS relies on the old dot reddit dot com layout (and goes to there automatically), so it might stop working if we lose old reddit.
The other thing is that I tried PDS and have had a very bad experience with it. Compared to the scripts out there like shreddit, I found PDS to be unreliable (no way to verify it deleted successfully if a rate limit stopped it, also it doesn’t save all content and returned a truncated CSV file).
