Summary: For years, Google and YouTube have included a trusted flagger program by which certain entities that have shown they “are particularly effective at notifying YouTube” of content violations are given more powerful tools with which to do so.

This is used often in the copyright context, and companies with a good history may be given access to things like bulk flagging tools and priority review of flagged content. One such trusted flagger for copyright was a company called Topple Track, which offered an automated service for musicians, searching the internet for infringing works and dashing off automated DMCA notices.
