Create an api.php module that lets bots like EranBot submit copyvio information to PageTriage
Only bots with the pagetriage-copyvio right would be allowed to do this.
Create "copyvio" PageTriage tag and populate it with a positive value when the API is called. The value can be 1 but it can also be the last revision id for which copyvio was detected, if it can be of any use.
