what is unbound specific is that unbound answers rd==0 queries which IMO
it should not and which made this entire pointless thread possible.
(dnscache seems to have not suffered for its decision to drop all rd==0
queries on the floor.)

other examples of user stupidity include publishing howtos like this:

    http://www.howtoforge.com/installing-using-unbound-nameserver-on-debian-etch

which recommends the following ACL:

    access-control: 0.0.0.0/0 allow

this one is a bit harder to prevent since really obstinate users can ask
for two /1's or four /2's...
