If you have open WiFi how can you block wifi extenders from being used on your network?

A WiFi Extender doesn't care about CWP.  Once it has its Layer 1 connection it acts as neither a source or destination on layer 2 or 3.  So blocking it by MAC or IP has absolutely no effect on those who connect through the extender.  Those using the extender get DHCP and the CWP from your network and unless you can figure out which clients are going through the extender you can't block them either.
I could figure out which clients are actually in the building and go from there.  As soon as those crates of "Extra Time" I ordered off of Ebay show up I will get right on that.  But until then it would be nice to figure out something else.
As per the people in charge, the library provides free wifi for patrons of the library.  We can't afford to act as a free ISP to anyone with an extender.
I really hope I am missing some feature of the Aerohive that can take care of this little issue.  Any help is appreciated.  Thanks for your time so far.

Instead of an open network, how about a self registration cwp with PPSK. Or if it's not too inconvenient, utilize PPSK to change the WPA key on a daily basis and email the key to the librarians to post in the building.

Best,

I will look into that.  The self registration cwp may be acceptable.  We already discussed changing the key and even changing on a weekly schedule was unacceptable.  Thanks for the reply.
