Contact at spamhaus to ASK for a DROP listing ?

[Carlos G Mendioroz <tron () acm org>]

Hi,
I've seen many threads of delisting requests here, and this is NOT one.
I happen to be tech contact for an unused allocated block that has been 
recently hijacked. I have no means to actually route it now, so I guess 
the best course of action is to list it in DROP. On pourpose.

If anyone can help me on that, or provide advise on a better course of 
action, I'm all ears :)

TIA,
