Good point. I guess testing the NickServ level would be the ideal way since 
checking for a status of 2 would find if the nick was recognised by access 
list only with a status of 3 for identified. 

If the access list is too vague it could lead to similar problems with 
popular ISPs and there is little to stop someone adding in a whole set of  
masks so maybe it is worth ignoring anything but fully identified nicks.

Recover and release would work in any case so might not be a huge problem 
and may encourage users to identify.
