I think it may just be Reddit being inferior software, but it happened to me, too. I have been Googling “Reddit “ and my username, deleting what comes up, and doing the search again in a couple of days to see if it stuck. (Deleted comments will show up on Google for a few days because of caching, so there’s no point in checking immediately). It takes a while, but it’s fairly reliable, and it can be done in small batches.
Regardless, using Shreddit + my GRPD export is working! It’s slow, but it’s absolutely working!! I’ll let it continue to run overnight and that should be that! =)
Mine ran pretty much constantly from thursday night to this morning to remove 60k comments (although script crashed once on Friday and Sunday at0200 for isp.resets while I was asleep so not quite full time)
(One tip if it does stall make a note of the comment I'd it stopped on and clean out the copy of the comments.csv the script uses above that point. That way it is not starting again)
Ok, it did stall after about 16,000 comments. Is it ONLY the comments.csv files that needs to be edited because there’s another file (comments_headers.csv) that seems important. LOL
Assuming your using the https://github.com/andrewbanchich/shreddit script then it uses the comments.csv as it's reference not headers. If you are doing posts as well then that uses Posts.csv
