Well, it seems that this website has been visited by Pakistani spammers. These are the people who leave irrelevant comments with links to their own sites, in the hopes of tricking people into visiting them.

Well you Pakistani spammers, I'm on to you. Unfortunately for you, I've got comment moderation turned on, so you won't see anything you try posting until I approve it...and I'm not that generous.

And, I've firewalled you off. Unfortunately this means throwing the baby out with the bathwater, so your actions have the consequence that your fellow countrymen who want to visit me can no longer do so. And it's not that I don't care about Pakistan, the thing is that I'm not expecting any legitimate Pakistani visitors, so it's easier to justify firewalling out part of Pakistan than it is for me to waste my time deleting your drivel.

Sorry Pakistan, that's the breaks...
