StumbleUpon Exchange (suexchange) is a new service that allows you to post your sites and have them stumbled by other StumbleUpon users.
You earn "Points" by stumbling other user's sites and you use them by posting your site to be stumbled and having your own site stumbled. You can verify each stumble before you reward Points. You are given 3 Points on sign up, which you can use to post your site to be stumbled. Each stumble they give you cost a point, but once you verify they've stumbled your site and given them a Point back you get a Point. This way the stumbles keep coming as does the traffic!
This is a violation of most ad networks and can get you banned. This is considered a invalid impressions and\or traffic exchange program, you can view a huge thread about this on digital point regarding the mass banning Google AdSense did back in November for particapants in another SU exchange program.
You do have AdSense ads on that site, and the site nowhere states that it might get you banned from ad networks. Which gives the impression to beginner webmaster that it is ok.
I'm stating this for people who wouldn't know better, which you did not do. Also, most SU exchange program's websites get banned from AdSense as well due to the fact of what they promote. You'll get the famous "in order to protect our advertisers" or "your site(s) don't match our advertising criteria" letters from AdSense. Don't say I didn't warn you.
You should also mention that using this type of service can get your site banned from Stumble Upon as well, failure to use a correct disclaimer can bring legal actions in the future, just another tip.
I mention this because none of your sites operate as their own entity (LLC, Corp, etc) and that all your assets would be at risk for losses related to this one site.
