best practices dealing with lame delegations

[Ken]

I'm looking for a way to deal with lame delegations.

There's an old script called lamers.sh that will email the hostmaster of 
a domain. I really don't want to automated any kind of email these days.

Also, the hostmasters in question are not likely to care, or understand 
a word of this.

I'm tempted to resolve the domain to a parked page full of google ads, 
or to resolve it to 127.0.0.1, or even to the registrar's NS - since 
they don't seem to care either.

None of these options really seems like a good idea, so I'm left 
thinking perhaps I should just stop logging lame delegations. Is that 
current best practices? :-(

What do you do when you are being swamped by a lame delegation?

Thanks,
Ken
