Forums Scripts & Popups channel url ban PROBLEM

i have this script that was working well for awhile but somehting has happend and its not working. I also want to add 2 other links that are acceptable to the channel but still ban any links other than the 3 i want listed in this script.
http://www.darkthrone.com/recruit.dt?uid=
http://www.kingsofchaos.com/recruit.php?uniqid=
http://www.planetbattleground.com/recruit.php?id=
These links all have letters/numbers after the = that can be any variable. If anyone can help me i would greatly appreciate it.

You can fit it on one line if you want

(in short: find instances of http://www. with no darkthrone, kingsofchaos or planetbattleground behind or instances of http:// with no www after or instances of www with no :// before)

Yours will work to "some degree" however its very inexact, for example yours requires the spammer to 'spam' the url in the first word of the sentence.. either of the 2 posted here are great alternatives, although one more geek looking than the other *looks at kelder*

Spacing
This: if ($gettok($1-,-2,47) != www.planetbattleground.com){
Should be if ($gettok($1-,-2,47) != www.planetbattleground.com) {
