Send queries for domains that the server is NOT configured to accept
is very different to sending queries for domains the server IS
configured to accept.

You just cost the rw adminstrators time and money investigation the
source of unexpected traffic.  You cost everyone on the list some
time and money helping out the rw administrators.

The actual cost of the traffic in inconsequential to the other costs
that have resulted from your actions.  TLD administrators actually
need to look for abnormal traffic as they are high value targets.
