OK, tech experts: Seriously, should I be scared about this? Is my blog toast?

Received the following letter from Xinix World, a UK outfit:

Hello Joe

Since getting this alert, I've devoted all of my spare time to scouring this blog, deleting all spam posts I could find -- yes, even the ones from Generic Viagra -- in the hope of making the Xinix World folks happy. (You'll notice that I am not linking to their website.) But what I want to know is this: If I miss one or two (or, heaven forbid, more), what might happen to me? Will I disrupt the space-time continuum? Does Xinix World have the capacity to launch tactical nuclear weapons in my direction? Will Google shut down my freaking blog?!?!?!?!?

Help!
