Tons of people have used our domain name servers without permission.
I periodically audit the zones which claim to be served here. For those which have been delegated lamely, I create a *primary* zone @ 7200 IN SOA my.server. hostmaster.my.server. ( 9401090 ; serial 7200 ; refresh every two hours 3600 ; retry every hour 2592000 ; expire in 30 days 7200 ) ; default TTL of one day NS MY.SERVER. MX 0 lame.delegation.to.MY.SERVER. * MX 0 lame.delegation.to.MY.SERVER. randy
