Consumer ISP's who don't proactively take care of security/abuse usually
end up with harvesting-bots which consume significant amount of DNS
resources, typically doing anything from a few dozen to a thousand
queries _a_second_. A few hundred of these will seriously hamper an
usually provisioned recursive server.
