It IS mandatory or you cannot be a Contet Partner. This has been the rule sine 2009 when I started working with them. As I stated in another tube thread, YouPorn is the ONLY tube I do this for, every other tube gets the basic .com watermark.
YouPorn is still great for conversions so that's why I do it. There's a seperate YouPorn folder for each paysite with a re-direct on the index.html page with YouPorn's aff code. Now I do not know how many people type in
www.paysite.com/YouPorn as opposed to simply
www.paysite.com.
I do have a Stacounter code on all those re-directed YouPorn pages. It's a tiny amount, less than a hundred clicks a week.
