Tracking Code across Domains

Is there a way to track visitors across unknown domains? I am using Matomo on a HTML web page that my visitors sometimes steal to use on their websites and by embedding the tracking code into a JS file, it is my hope to identify the domains that are using (stealing) my HTML page.

Since it is impossible to know which domain(s) might steal my web page, is there a way I can get Matomo to display results on unknown domains?
