If your account is still active, I’d suggest PowerDeleteSuite. It worked well for deleting my thousands of comments for me.

It’s unfortunate you went about it the way you did since they can still monetize off of the entirety of your comment and post history. When you delete your account, all your comments and posts remain. They’re just no longer attached to your account name since that is what you deleted.

I was a bit more malicious and did the opposite by keeping my account intact, but gutting everything from within. So now every thread I ever commented in has “user deleted comment” sprinkled all throughout hundreds or thousands of threads.

My account is now a fine metaphor for what reddit has become. Just a hollow facade of what it once was.
