Dan Savage's Weird Internet Voodoo

Here's a thing. I have this very strict, yet strangely capricious, firewall at work. It blocks me all the time from seeing quite innocent sites on the basis of foul or inappropriate language or graphics. But so far it has never blocked me from reading the way-out-there column of sex advice Savage Love. Why is that? Does the writer of Savage Love (the exceedingly gay agony uncle Dan Savage) have some mysterious powers over firewalls? Or are firewalls basically just cr*p?
