How many freaking times do you have to kill file someone????????




If the person is a creative troll, he will keep changing his header info to
get around killfiles.

The best solution I've found (in Xnews) is to find something in his header
that is the same in all his posts, and killfile him using the score file.
It works a treat, because there is almost always going to be something
that's the same.

Then, never announce that you have successfully killfiled him, because
he'll find a way to get around it.
