And once again public perception plays a key role in individual rights
It is the advertisers themselves that has forced Youtube into the action, Everyone is monetizing their videos (This is one of the reasons Teds Videos keep getting copied and stolen) and there are advertisers that are complaining that their adds are being shown with video content they do not want to be associated with. Due to the fact that there are millions of videos that youtube has no way of personally censoring they have used broad spectrum filters to place these type of videos in a restricted classification. It would almost be impossible to create a narrower spectrum filters without dramatically increasing processing ability's as video filtering requires much more processing power than that of written text. In fact I would say that much of the filtering being done is by that very thing. The Title, The Description, and the Discussions not the videos themselves. Perhaps an added filter in speech recognition as youtube now offers cc for videos. So any KEYWORD Like Gun, Blood, Dissection, Or Hunting, Or whatever Keyword that the Advertisers have complained about has been flagged.
Michael flip the switch, If a sponsor called you and told you someone has posted a video showing there product being used doing something that they do not agree with and posted a thread about it, and threatened to pull their sponsorship if not removed you would have to make some hard and perhaps controversial decisions.
