It generally works better when you setup a domain redirect, it looks more professional.

Or consider building a list with a squeeze page, that works great!

Ok, but I have read of users banned, youtube in its terms does not allow links to affiliate programs. However, I know that there are also thousands of users that have not been banned.

Is that correct?
With redirect it's also a possibility to be banned?

Thanks

Yes. I saw so many direct linking to affiliate product from top Videos. But I am not sure. Why taking risk? Use a domain instead
