Answer

Why do criminals sometimes turn AIS off or spoof signals, and how can Mallorca counter this?

Criminals manipulate AIS signals or switch them off to avoid detection, especially in busy shipping lanes. This makes tracking harder and can enable mid-Atlantic transfers. Mallorca can counter this with geofencing, anomaly detection, and automatic alerts that prompt quick inspections.
