I want to know the answer to the following question:
Who checks the flagged videos for unauthorized content?
All the background I'm provided with is that "In July 2008, the Culture and Media Committee of the House of Commons of the United Kingdom stated that it was "unimpressed" with YouTube's system for policing its videos, and argued that "proactive review of content should be standard practice for sites hosting user-generated content".". Is that enough to answer the question?
Answer: no
