@noybeu Specifically, as far as the Irish DPC was concerned, “all data associated with the account being rendered unavailable through Twitter’s production tools” was enough for them to consider Twitter’s obligations under GDPR Article 17 to be fulfilled and for the complaint to be “amicably resolved.”
At this point we’d had several back-and-forths and I decided it wasn’t worth my time to pursue it further given the Irish DPC’s clear lack of desire to enforce GDPR Article 17.
