Please stay away from such services. It is not worth the time wasted. Guest posting and articles marketing, commenting and easy and quicker and geta lot of results.
While it may be "worthless" traffic in most cases, here's a tip to get more credits: Click on sites that have no "likes" showing and avoid the "Pro" links. 9 times out of 10 you will get 2-5 credits instead of just 1 per click. Surfers on TS are looking for traffic so offer them traffic generators. Anything else is very unlikely to get you any worthwhile traffic. Sure you'll get the occasional buyer for anything under the sun, but the main thing 99% of surfers are looking for is more traffic. If you are going to waste time at least get the most out of it. Click on the least favored links to get the most credits. (most people click on the most popular links instead)
One of the big names internet marketers online, ( I am not going to mention any names), recommends them on their site and I can see that they are using it. I personally have now mixed emotions about them. I don't know. Maybe if you buy credits from them you might get a few sign ups here and there.
