Alvarus:

What's the user's fair share when the company is providing hosting services for free?

Any part of an actual profit. Hosting for free is nice, but so is not paying for content. As for actual percentages, I don't really know to be honest, but its something that should be worked out.

And as for the "Naruto montage thing" well, that is a different story. I'm more referring to the "Christian the Lion" and "chocolate rain" type of content.
