As a user of Apple products I have never come across any such list maintained or shared on websites by any Carrier or Apple Inc.
Find My iPhone includes Activation Lock—a feature that's designed to prevent anyone else from using the user's iPhone, iPad, iPod touch, or Apple Watch if it's ever lost or stolen. Activation Lock is enabled automatically when the user turns on Find My iPhone.
Activation Lock helps the user to keep their device secure, even if it's in the wrong hands, and can improve the chances of recovering it. Even if the user erases their device remotely, Activation Lock can continue to deter anyone from reactivating the user's device without their permission.
