OK, I've had enough of these guys. And from the look of it so have many other people - including silverstr.

I generally approve of all the work going on to rid the world of spam, but these guys are so arrogant. Statements like: nobody with a dynamic ip should be running servers or are incapable.

Dynamic IP are a fact of life! Many BUSINESS broadband accounts provide their customers with fixed ip using long term dynamic leases. Of course they will still end up listed! Network range blocking is not much short of technology discrimination.

Just because my servers run from a residential broadband account does not make them insecure. During the course of my career I've been involved in the networks of many organizations and I can sleep safely knowing that my own boxes are a tight as that of many them (which in a scary side note, is not as tight as you might think).

All I can do about the situation

• is ask for mail server admins not to use this service - you will lose real business otherwise!
• congratulate the masses with their continued DDoS on these guys

There are better blacklist to use, run by organizations with some idea of how the real world operates. I personally use SPF records to limit the addresses spammer can use (not mine basically).
