When I first set up my YPN account I forgot to block the RON domains. Earnings were fantastic. Then I remembered and added vonage.com and a few others. Earnings dropped big-time. So I removed the block on vonage.com and I'm again enjoying unprecedented earnings.
I just removed the blocks after reading your post! :~ )
Thank you too, nathanso. The insights and experiences you've shared are very helpful and got me thinking outside the box!
