We have affiliates and we check for fraudulent activity. Even after we cancel an account they are still sending traffic. The URL for the affiliate to receive credit has the variable "username=XXXXXXX" where XXXXXX is their username. I would like a page where I can enter usernames so that when a URL comes to the site with that username it is filtered out and not allowed to create a click through. It would be best if they were routed to a page such as "[url removed, login to view]" instead of the search page. I need to be able to enter as many usernames as necessary and see a list of them on the screen in the admin section, with the ability to delete or add new ones.
