This site is only 1 week old and they pay on Net45 schedule so there can't be any payment proof. Also, there is not much info on the website. Also, they require a company name Maybe it's a good idea that you join and try them out
They look legit. Their website is well designed and they do have company information which can also be a plus.
I am trying a handful of CPM ad networks right now. I have been using Adcito since May. I just received my first payment because they pay net 45. The earnings have been good so far. The payment was on time. They switched their dashboard about two weeks ago. The new one is easier to use. I like them so far.
