Privacy regulators in Ireland have launched an investigation into exactly how much data Twitter collects from t.co, its URL-shortening system.
The investigation stems from a request made by a UK professor named Michael Veale under the General Data Protection Regulation (or GDPR), a comprehensive European privacy law that took effect in May. Under the GDPR, EU citizens have a right to request any data collected on them from a given company — but when Veale made that request to Twitter, the company claimed it had no data from its link-shortening service. Veale was skeptical, and wrote to the relevant privacy regulator to see if Twitter was holding back some of his data.
