Hello, to be upfront and straight forward, we've not been able to get in contact with any of these networks so we'll just cut the networks out and pay you the webmaster directly more for your banner ad placements. If you're interested and don't want to post publicly, just shoot me a PM with your information and prices they are paying you. We will pay you more for your placements! Besides, why would you want to work with a network that you can't get in contact with?
