Just switch off recursion on your server then they are forced to either
choose an open resolver or run their own namserver as resolver.

If they delete any forwarders from their /etc/named.conf then they do
query only authoritative nameservers starting with the rootservers and
rarely ever touch your nameserver most of the time.
