I've enabled trackbacks again on Knews thanks to this module patch from Bill Katz which provides a temporary solution to the problem (well, until the trackback spammers get more aggressive). The code now contains a filter for "evil_words." So if you are sending a trackback to Kairosnews, you'll have to refrain from using the terms poker, psxtreme, freaky, howtoplay, holdem, casino, terashells, and phentermine. ;-)
