And btw, most of those videos are freely available on youtube already. And no one bothers them - they see it mostly as welcome promotion for their official copies of obscure films (hence my name) which wouldn't otherwise sell at all.
Trust me on this, I'm a professional film director and producer, I know these things. This is seen as free promotion.
You really believe that making Dtube more restrictive and limited is going to help the platform while trying to compete with the established ones?
