I'm a fairly newbie affiliate but I was pretty honest in the questioning process. They just sent me an e-mail saying that based on my answers, I did not qualify for approval.
So what's my next move if I want to run pop. PopAds?
if you want fast data and progress, start with adcash (you should have at least 1-2k for testing, otherwise you will burn to fast through your budet).
Popads is great. If you have 1k for initial deposit and subsequent top ups, try propeller, then gunggo, then adcash.
Propeller is my favorite - their traffic quality is great. Adcash has a ton of traffic but you need to throw cash at it to weed out all the bad placements before you can profit - it's sort of like the "Exoclick RON" of pop traffic. 
And Gunggo is good as well - depending on who you talk to, they may ask for a 5k initial deposit. If you want to get in for a lot cheaper send me a PM and we'll get you sorted.

I was in the same situation as you. As suggested above, skipped them cause there are plenty of other networks.
ZeroPark is a reseller. You'll be buying propeller and adacash with a margin. I have a data to confirm it.
me too, not approved to zeropark,
