I played with the python PRAW package to scrub old comments a while ago. Even iterating through the different sorts (new/hot/controversial/etc) I could remove everything there, but different comments would appear there after some time.
My theory was Reddit ran batch jobs on some cadence (daily maybe?) to generate the topN comments lists for each users profile page. Running my script a couple of times over a several days seemed to clear everything.
