User blog:JoshuaJSlone/Wiki Policy: Which videos are appropriate?

In the last few days I've been working a lot with Berryz videos, adding more into the Additional Videos sections from their official YouTube channel. There were others already on the pages that weren't from the official channel, just ones other people had uploaded to YouTube at some time. Nothing new, just something I ran across a lot in a short period of time, and with a bit of the conversation from the Taiki Bansei page's comments section in mind--about how videos ripped and shared are piracy when you get down to it.

So should our policy be to weed these out, and only display those that have been officially shared? And if we do so, would it be hypocritical to make an exception for the videos from groups/soloists who predated the time of official YouTube presences? Certainly it seems to me that a 12 year old Minimoni music video and the (Dance Shot Ver. II) from some modern limited edition DVD are different cases, but I'm not sure the best way to rationalize it.
