YouTube just launched a program that rewards volunteers for enlightening the YouTube community in various ways.
Participating in the community gains users reward points, and there are five tiers of heroes. Points are awarded for flagging videos as part of the YouTube Trusted Flagger program. The Trusted Flagger program is invite only, and gives select users more advanced flagging tools. Users can sign up for the Trusted Flagger program here.
Points are awarded for adding subtitles and captions to any videos. This makes the videos available to more people, including those who cannot use speakers, or those who cannot hear. Helping out other users and responding to queries on the YouTube Help forum also awards points to Heroes.
