I’ve had a lot of my ads placed on entrecard rejected. I was wondering why people are doing this. After some research i’ve found that people are gaming entrecard. You get paid in credits for placing ads of other bloggers on the widget. In the beginning, you only get 2 credit/day but your ad space quickly goes up in price once you start getting more ads. What people are doing to game entrecard is…they take the ads and after 30 mins or so, they remove the ad. This gets their ad rate up and they can receive a higher rate per day. Then they take new ads at a higher rate. It’s very annoying and i hope graham gets to the bottom of this.
