Exactly. What’s the limiting principle here? Can anyone who asks get their info blocked? A world in which we can’t verify people’s schedules is a world which requires a very high degree of trust in crew scheduling. My trust in them is as close to absolute zero as allowed by the laws of physics.

If the company can’t block said pilot’s contact info only and leave the schedule available for verification purposes, that sounds like a “you” problem. Either spend the money to write new DOS code and allow it or have said pilot file a lawsuit and win bigly. Their problem not ours, keep your deals, etc etc.
