Okay, that's it

Okay, that's it! Screw the blacklists. I'm killing your domain "dvsoo7@hotmail.com" who "owns" "www.best-online-casino-directory.com". You spam my blog, I have my DNS servers declare themselves authoritive for your domain. What this means is any of my users trying to get to your site ends up on 65.174.230.39, 164.109.48.78, or 209.16.87.50 (or anything else I can come up to use in a round robin).

For those that don't know how to do it, here's the method for BIND:

First declare the zone in your config file:

zone "best-online-casino-directory.com" {
type master;
file "db.spammer";
allow-update { none; };
allow-transfer { none; };
}

Then build your zone file:

$TTL 86400
@ IN SOA @ you.yourdomain.com (
2004011401; serial
3H; refresh
15M; retry
1W; expiry
1D ); mim TTL
;
; ## Poison MX Records ##
@ IN MX 10 localhost
; ## Poison A Records ##
* IN A 65.174.230.39

Restart your DNS service and that's it. Anyone who queries your DNS server will not get the site they're expecting. (Hint: you may want to be careful using those IP addresses. Point a browser at them first.)

Oh! And be careful using this method if you sell service to general users. I'm able to use this method because of the existance of a security policy that says "no porn/no gambling from your workstation".

Mr. Gage of 1401-C Skyridge Dr, Crystal Lake, IL: pay the advertising charges I have posted on the front page of my blog and I'll re-enable the domain for the 35,000+ users my servers resolve for. Otherwise you become the 21,453rd poisoned domain in the server.
