Interesting!
Who retains ownership or may I say full administrative control ?
Also, what kind of ads ?
Logically if hes registering domain and retaining full control of them, then its of no use, because anytime it can be just pulled away, so once you work hard and make domain popular, you suddenly loose it, besides visitors.
So, such information is important.
Also, no terms mentioned.
Kindly provide more details as website itself is not providing required information.
thanks,
