copy existing list circumvents list approval process
the create_list_request form has an option to create a new list based on an existing list, if the user is an admin of any lists. this creates the list immediately, without putting the list into a pending state.
for now, i disabled that part of the form and also disabled the function in wwsympa (someone managed to submit a request for this after i had disabled the interface for it...)
