Is dynamicoxygen.com Safe?

This web site is a member or user of the "DynamicOxygen / ExitJunction" sites which offer a browser exploit that hijacks browser Back-button functionality by manipulating browser history to redirect visitors to unexpected locations when trying to leave a site. This is considered very bad practice. When you visit a site which has installed ExitJunction code, the code downloads the exploit from exitjunction.com. Then when you use your browser's Back button, you could be redirected to a dangerous site. Reference: *****

Dynamic Oxygen, LLC. owns the "back click jacking" network called ExitJunction. "ExitJunction - Your Innovative, Non-Intrusive, Exit-traffic monetization solution! Visitors that find your site through a search engine eventually leave your site by hitting the "back" button. The question is, are you making money from this exit traffic?" I'm not sure how they can consider non-intrusive as being directed to a search engine page that you never intended to land on by clicking your browsers back button.
