Well I just got my first phone calls and it was no big deal at all and was easily approved.
I first signed up at copeac a few days ago and didn't know what I was doing and when they asked for a site I put the site I wanted to put ads on which was a basic plain site and probably didn't answer the other questions like I should of.
So I didn't get a phone call, instead the denial email about 3 days later.
However, after reading a few threads like this I knew how to respond to the questions. I put up a nice site that says I am an "Internet Marketing" company and then applied to a few places that were suggested to me like copeac(again), market leverage, xy7, neverblue & a few others.
A few called the next day & few I called and each only took a few minutes on the phone. They didn't really ask for much details and all approved.
