Only jurisdictions with verified evidence (or a verified survey answer) appear below. Absence from this list means “not yet assessed”, not “no”.

🇪🇸Spain Partial / committed
The 2026 tax control plan (BOE) gives preferential enforcement attention to business models built on social networks — influencer marketing gets its own section (A.5.4) — but this targets social-media businesses rather than general monitoring of taxpayers’ accounts.

🇮🇹Italy No — power absent
The Agenzia delle Entrate officially denies any mass collection of social network data, stating Italian law does not permit acquiring data from social networks by such procedures and no such initiative has ever been adopted (May 2026 statement; Law 132/2025 also bars AI-generated administrative acts).
