Definitely not me, I do better with CJ, but a friend of mine as well as my mentor does pretty well with CB about 20 K a month. I assume he also not the top earner either because other claimed they had made 1 K or even 2 K a day with CB!
But seriously. You ARE wasting DP's bandwidth by posting such thread. You could at least tell us WHY you'd like to know
If we talk about publishers, then it's probably Water4Gas owner I can't even imagine his Clickbank account... If we talk about affiliates, then it could Ewen Chia. He is known as number one affiliate in the world...So could be him
Clickbank needs investment. If you can afford to advertise in Google Adwords, then you may be able to get back your investment.
