No, I've got that. I read the directions you already had in the comments.

I've got this:

function checkBlurb() {
var whiteList = new Array();
var blackList = new Array('Loki/Tony Stark', 'Steve Rogers/Thor', 'Podfic');
var whitelisted = false;
var blacklisted = false;

Maybe it's successfully blocking things that have all three of the tags, but it's not blocking things that have the individual tags.
