I just realized I have trackback spam on my site. *sigh* Why are these spammers interested in creating dead hyperlinks on people's websites? What do they gain by putting a dead link up all over the internet? Dead links won't raise their Page Rank on Google. Or if it does, it won't do them any good, as everyone will link to the dead page.
What about people is it that causes them to ruin things for other people? As a child I often was picked on (ruining things for me) just so some other people could have some fun. I guess its the same idea here. Morons.
