Ok alot of changes have taken place since version 1.0 namely the email list and the stealth feature.
Email list: Allows you to add your own 'live' and 'legit' emails you have scraped or obtained through purchasing or a squeeze site.
Stealth Feature: Although I still have the blanked referrer feature left in I also have included this stealth feature that allows you to Produce (Impressions, Clicks, and Conversions) on your offers now this also passes the page the offer banner is located on as the referrer so you produce a trackable source of traffic for your offers. This was added since alot of networks these days get pretty upset and ask alot of questions about blanked referrers and some just straight up and ban you if you blank. I strongly strongly suggest using this feature rather then leaving it turned off. because it will save you alot of headaches in the future.
Is it worth it to buy? That is a question you need to ask yourself. With any blackhat method or tool there is a risk of losing accounts, and this tool is no different. I do however try and take as many precautions as possible to make it as safe as it can be.
On the Topic of SD3 + CPAX.... SD3 is not needed for the functionality of CPAX and doesn't effect it in any way. Alot of SD3 users are also CPAX users and vice-versa so I added support for SD3 to be used along side CPAX as a additional tool to help you distribute your exe.
CPAX isn't PPI but is closely related due to the fact that you need to gain installs for CPAX to work properly.
Like a few others have said here, stay under the radar, if you are not producing $100/day on each network already, don't come blasting out of the gate the first few weeks you have CPAX and try to earn that. Set the throttles to maintain a acceptable earning and slowly increase it as time goes on. This will allow for a more natural and organic increase of your performance on the networks.
Actually now is the best time to jump off the fence if you are going to, as we are running a thanksgiving promotion where CPAX = $300 and SD3 = 150 so you can get both of them for $450 total, saving you a few dollars if you get it during the sale.
Also please note that JV's are not permitted on the CPAX system, your account will be deactivated.
