If you go back to the end of 2009 they were pulling some dodgy shit back then. They were sending CCBill affiliates traffic to join pages with Epoch billing that wasn't being credited to the affiliate.
Their solution, provide a second join page for the affiliate(s) that complained about it. I'm not aware that they publicly made an announcement to all affiliates to change links. They also didn't change the links on the FHG.
It also looks like they didn't notify affiliates when the decided to change the link again and it now doesn't exist and redirects to tour5, which has the Epoch billing.

I dropped them and pulled all links in 2009 because of this dodgy shit they were pulling.
