I just wanted to share with you my bad experience with Zeropark. This is a company that sells push, domain redirect and popup traffic.
I've signed up as new advertiser with $200 deposit. I run 2 popular verticals - gambling and men's health product using their domain redirect with targeted keywords, full page popup traffic and RON. I also used their whitelist provided by Zeropark manager for gambling vertical. My ads generated over 9,000 clicks with 0 conversions.
After testing and spending $145 on useless traffic I requested a refund of the $55 balance but the Zeropark manager refused it saying that the 1st deposit is non refundable... I disputed it with PayPal and Zeropark suspended my account the next day stealing the remaining $55 balance...
I believe that Zeropark traffic (almost 10,000 clicks) I paid for was fraudulent (bot traffic) therefore I would not recommend their marketing services to any advertiser or affiliate marketer.
