License terms violation

A CC license terminates automatically when its conditions are violated.

For example, if a re-user of CC-licensed material does not provide the attribution required when sharing the work, then the user no longer has the right to continue using the material and may be liable for copyright infringement. The license is terminated for the user who violated the license. However, all other users still have a valid license, so long as they are in compliance.

Under the 4.0 licenses, a licensee automatically gets these rights back if the violation is fixed within 30 days of discovery.
