Is there some script, addon or something that will take data from GDPR request and delete content, especially comments, one by one? redact had this capability, but it's not working now
update: https://github.com/andrewbanchich/shreddit worked, removed 9500 comments after 18h or so
It can be done with shreddit: https://github.com/andrewbanchich/shreddit
It has a built-in option to point it to your extracted GDPR data, and will edit and/or delete all the comments that are listed in there.
Just configure it according to the instructions, and then let it run unattended for a while. It took about 15 hours to delete the 13000 comments on my 12 year old account.
