Just thought I should post a warning about blazingtraffic.com - I don't claim that it's a total scam but you should at least read my mails with them before buying anything from them. (Blazingtraffic is low quality traffic that I just thought would be worth testing but it was not according my logs)
You can tell if traffic is real or not by trace routing the IP addresses of the visitors. Fake traffic will have very high percentages of anonymous proxy addresses or dead-end/not-in-use IP addresses. If the traffic is being generated through an auto-surf exchange or if the traffic is being auto-refreshed, you will be able to tell by the length of the visits. If you see that all of the visitors are staying for exactly the same duration of time, then odds are is that auto-surfing or auto-refreshing is to blame. Auto-surfing and auto-refreshing is not exactly 'fake' traffic, but auto-refreshing traffic is unethically generated traffic (traffic generated by the pop-under being auto-refreshed to show a new ad every X amount of seconds). Auto-surfing traffic can easily be categorized in the junk traffic bin. People that join auto-surfing programs are forced to view a new website every X amount of seconds in order to build credits in the traffic exchange. These people are more than likely not interested in your site, but interested in earning a credit from the exchange. In fact, most of these programs are totally automated, meaning that the program will surf websites automatically while the member is not even in front of the computer.

I most certainly do understand this and I do know my position about the issue (read the quoted mails) but I don't want to claim they are scam because that might have legal issues so I only state my personal opinion. (which is that if all visitors have same ip and exactly same user agent, they are from same computer that runs a script) That's not wholesale, traffictaxi wholesale prices (the source you are using to get the traffic) are lower than that.
Blazingtraffic is a scam. They had claimed to have sent over a thousand visitors when Google Analytics had counted less than 10. I threatened to charge their fee back to my credit card. They then offered me a refund. You've been warned.
