Today an New York based ISP spammed our entire customer base. The
culprits are:"
Easyway Communications,Inc.
(www.easyway.net)

I sent them a bill for the delivery of the mail (which I'm sure they will ignore)
a) what more can I do?
b) is it possible for us to treat such people by collectively routing
   their IPs to lo0 ?
