Ahhh ! now I see what u're trying to do. In fact I suspected that you might be doing something special about your frames. In my previous reply I nearly wanted to ask you HOW big your frame is or HOW many frames you have within the framer page ! Because if your answer was going to be anything other than ONE simple big frame, then I was immediately going to know that you're doing pure blackhat stuff , Lol

Anyway, now I see! it must be that you want to LOWER your CTR rate/ratio or inflate your legitimate traffic (from a totally separate/unknown source) by diluting it with a sizeable amount of junk clickthrough traffic or rather forced-click traffic
Sorry to say this, but this sounds rather more and more intriguing to me as I think deeper about it
My biggest worry is the idea of guys trying to "hide" the source of the traffic COMPLETLEY. There is NO good reason to do something like this, with CPA Redirector. Trust me, there is none.
There are some things that u may need to clarify though
So this is your setup :
Junk Traffic -> Framer/outer Page -> Framed Page 1x1 px (CPA Redirector) -> Offer Landing Page
The mere fact that your CPA Redirector is running inside a 1x1px frame tells me that you are doing something that's NOT necessary, Lol. It means the visitors do NOT see the offer page. And yes I know you DON'T want them to see the offer, you probably DON'T care about them seeing it, because you're thinking of these visitors as "junk traffic", am I right ??
What you are doing therefore is something related more to "cooky-starving" rather than hiding referers. There is a small relationship between these two topics, especially with regards to referers and cloaking, but they are two totally separate blackat techniques. CPA Redirector is NOT a cooky starving technique/tool. With cooky-starving, you are essentially forcing people to click a link , or rather let's say it concisely....
You are forcing visitors to LOAD A HIDDEN SECOND PAGE that they are NOT CONSICOUSLY AWARE of it loading in their browsers while all they see is that they have arrived at a page that interests them and that they expected to see. Now that's cooky-starving, pure hardcore blackhat ! Wicked stuff ..Lol
I don't know if you have resources on cooky starving. I have a full-pack of cooky starving tools (about a 150 MB) and techniques, scripts, etc, but I may Not have the patience to upload the whole 150mb collection (unless you BEG me for it

lol )
If you'd like to stay with CPA Redirector (which is more of a referer cloaking tool than a cooky starving tool), you'd have to add a layer before your whitehat page in order to have the RIGHT setup and to have absolute clarity of what's happening in the flow of your junk traffic. Rather than obfuscating the path of your junk traffic with a 1x1 iFrame that happens to be your CPA Redirector ! You might want to put a doorway page (Don't worry about what doorway means) that acts as a randomizer. I'll explain below.
Example :
You send the junk traffic to mysite.com/folder/index.php
Now this index.php is your randomizer page
When they hit this page, it randomly selects a redirect destination
It selects between 2 destinations
It selects to send them to either to your whitehat page or to the CPA Redirector page
You can have your CPA Redirector page as mysite.com/affpage/index.php?magicnumber=27633
Now since your traffic "is junk", I assume it will be in large quantities!
With this method, you will obviously lose HALF of the traffic to your whitehat page

As undesirable as this may sound, as a blackhat marketer, you'll need to build this sort of mindset into your strategy. Even SENuke X and Scrapebox do NOT do 100% account registration or 100% SEO submission. The failure rate is pretty significant, around 40% failure !
This half of traffic you're losing will end up seeing the CPA offer landing page, so they will get automatically redirected to the offer page
They will close the offer page as soon as it opens since they'll hate it when they see that they've been redirected to land on this "acai berry weight loss product page" ! That's Ok !
You can now put a nice affiliate page (WITH BANNERS/LINKS!) as the BODY of your /affpage/index.php (yes that's your same CPA Redirector page)
This is so that when the affiliate manager/network visits this page /affpage/index.php they would see NOTHING sinister going on

They would just see it as a legitimate affiliate page on your site with typical banners/links directly linking to the offer.
The advantage of this method is that your setup will work in the manner that is condusive to CPA Redirector. CPA Redirector is designed to work "in this style". If it leaks the referer when setup in this manner, then I'd remain shocked like a monkey! You will have NO iframes or fancy double layers on a page with a hidden 1x1 frame or forcing people to load a hidden iframe.
The disadvantage of this method obviously is that your junk traffic will be split two ways. You'll lose half of that junk traffic since you'll be forcing almost half of them to the CPA Redirector page, which will immediately redirect them further to the CPA offer page and they will SEE the offer as humans and obviously close/dismiss it.
Yes I know, NOW that I'm saying the traffic should be randomly split, you might tell me that "NO my traffic is NOT actually junk at all" , lol ! I've thought about that too

I suspect that your traffic only becomes "junk traffic" if it lands on the CPA offer, otherwise it is NOT junk traffic after all if it lands on your whitehat page. If that's the case, then I must say .. you have a very fancy setup

But like I said about the mindset above, you'll need to be a resilient person if you want to succeed as an online marketer. Sometimes you'll need to throw away HALF of the apples out of your basket in order to be able to lift the basket high enough to load it in the truck
The alternative is to go full-blown cooky-starving. A topic for another day, another crowd, and another forum/thread ! Good luck.
