Because Matt moved, thus breaking the Pie Filter I wrote for his site, I've been forced to write a new one.
So, download and install, if you wish (you’ll need FireFox and Greasemonkey, first). You’ll have to do some minor editing on the script itself - to add your list of targets, and optionally, to change the comment-abusing style. Again, all the stuff you need to monkey (get it?) with is clearly commented.
If you’re using FF v2.0 (or 3.0), and you’ve installed GreaseMonkey, and installed this script, just go to the Tools menu, choose GreaseMonkey / Manage User Scripts, select the script and click Edit. The things you need to edit are right there at the top. It’s basically just a matter of changing the default ‘baddies’ names to the names of the people you want. You can have as many names as you want. If you need more help, feel free to ask.
