Rex, stop using gunggo (zedo). they are such a scam also. I had few legit sites with their ads. few months ago. never got paid. in the first days they counted one site of mine with big traffic and had nice revenue. later the revenue went to 1% or less (think about it) of what i would made in the first days. they said is an error in counting that ad... later after that, they don't reply to chat, they are mostly offline after you sign up. i didn't got paid, removed their ads after few months...

today i received an email from adnetwork to join them... i don't know. their site have a nice alexa, one year old, don't know if they are trustable...
