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?
Power delete suite only deletes comments visible in your profile, and if you have more than the profile is able to display you’ll need to rely on the GDPR request file to manually delete the rest. I’ve had to go through and do that, since despite my profile showing nothing checking some comment links from my GDPR showed that there are comments that weren’t deleted due to reddit comment display limitations.
