Their CPM rates seem alittle high and http://whois.domaintools.com/ecadv.net I would recommend staying away from them as they have only registered the domain for 1 year.
I'm just saying any serious business would register their domain for more than a year if they really wanted to be considered as 'serious' if you get scammed please do not come complaining on the forums.
hello! ecadv.net not count impression correct! cpm for impression japan is 9.52 and ion website me 350 visitor from japan and in account ecadv.net 0.01 cash! Dear madaflorina, Welcome back our member aera Total cash : $ 0.01 Total Paid : $ 0 ecadv.net is scam
That what the admin said when replying my email: Some members asked we whether the money they earn are less than the cpm price, 　　we have to say: the price is maximun price for the members who are not selling junk traffics with 　　good clicks! 　　Moreover, we are not buying all traffics you sell as our Advertisers can select the where their ads be placed on! You have to know that if you want earn more, you have to give us more traffics or quality!
