It's better to look for direct push providers. Megapushes lie about everything that has at least some sort of a traffic.
They drive traffic out to their own profit at first, then they sell it to the webmasters.
They disclose all the campaigns with the volume and become your competitors, and even with a discount on traffic. Plus their affilliate marketers get favors during the moderation.
If you have your own private offer, you can drive your traffic here.
