He is doing a great job. I have placed 3 orders and am considering a 4th. Ive been doing Euro and US traffic and haven't been disappointed.
Regarding if the campaign is adsense safe, I only can say that my website is running this campaign for almost one and half month now and adsense is still up. If you are worry about the adsense, you can create a landing page without it... Also since it is bulk traffic, it is slower than other targeted traffic, but normally you will get about 400 to 500 in first 24 hours. It is also good for your website if you have adsense code on it since google don't link the sudden traffic jump All PMs are sent, If I miss you please let me know..
