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.
I haven’t tried deleting my comments, but I’ve seen a lot of posts about comments being restored, left subs being re-subscribed to, etc… the evidence seems to be mounting that Reddit is trying to prevent the loss of content by keeping users from removing their own content.
I’ve seen people talking about overwriting their content instead of deleting it. I think I’ll go that route myself soon, hopefully that will stay under the radar.
Even overwriting might be getting undone, but that’s the best way to try it.
