I was trying to make a point with the BBC comment, not being entirely literal. Taking the criticisms more literaly:
The links to Zeoh, archive.org and any other video hosting sites are provided because they are links to the actual literal subjects in question, so the 'reliability' of the host itself is irrelevant. I would liken this to having a wiki about Polar Bears, a link to which makes an actual real life Polar Bear appear next to you for verification.

Any reference to lego.com or any other corporate site, is provided as verification of claims to official connection with said corporate body. The site of said corporate body is therefor the best (only?) reliable online source for verification.

And as for IMDB, you've obviously never tried adding an entry to IMDB. That sh*t takes weeks!

I'm sure anyone interested would gladly add better citation than that present if you would suggest something.
