spam inside code

I can’t figure out where this is seeding from. If you were to view page source of a blog post, below the footer I get this:

(footer code)

<span id=”a0320″>oparino-bs.ru priceresults.соm</span><script>var c81d1=””; function bbec6(e81) {document.getElementById(“a0320″).style.display=(e81==”” ? “none” : “block” );} bbec6(c81d1);</script>

Example
http://www.millennium-mb.com/blog1/2009/12/08/how-to-deal-with-missed-appointments/

view source, and scroll to bottom of the page

Any help would be great 🙂
