I found a plug-in for Firefox that deletes all posts and comments from your reddit account. (Power Delete Suite). Now I am in talks with reddit, to have them delete my account and data.
They say that all content will be disassociated when I delete my account but I had them confirm that they won’t recreate it when I have deleted it. They still say that they will retain the IP used for creating the account. Not sure if this is legitimate data redemption after I have asked for my data to be deleted according to GDPR?
This is power delete suite. Shreddit (the one you dl from github and run locally, not shreddit.com) when fed with GDPR file will patiently and happily delete all comments one by one
Shreddit also works the same as PDS when you don’t feed it GDPR CSV files. All of the tools work the same way more or less. Shreddit requires API access though while PDS uses old.reddit.com and scripts on the page.
Also when I did feed github shreddit with CSV files, it would “panic” and stop every so many links. Sometimes it would get through a few thousand, sometimes it would do just one. I kept having to edit the CSV files and delete up to where it got to and start again. All in all I think it took about 90 or so attempts, over about 2 weeks, but I got there in the end!
