I have little faith in my country’s data protection officer who is responsible for handling stuff like this. I had to deal with them while making a complaint about reddit not complying with the GDPR by not allowing me to remove upvotes/downvotes in a reasonable manner, and also after manually deleting all my posts and comments there were still 2 comments that show up on my reddit profile only if it is viewed “signed out” (i.e. from an incognito browser), but not while I am signed in to the account. There is no way to delete them from within my account. The reply I got from them after several months was that since there was no identifiable data in those 2 comments and since after deleting the account it would show up as u/deleted that my case was closed.
The incompetence of my government officials (more so than any other country) would be a laughing matter if I wasn’t so angry about the whole situation.
tl;dr: My country’s data protection officer and office is a joke and I have lost faith in them to be able to handle anything. I am considering going directly to the Irish DPO if that is who meta ultimately answers to.
