In case anyone else needs this I decided to use the routes class. For instance, account is a folder inside the controllers and the second segment "account" would be the controller that has all of the functions.
Code:
$route['account/account/(:any)'] = 'error_mess';
Basically if someone tries to enter "www.somesite.com/account/account/add_user", the add_user being the function, they would be redirected to my set error page!
