Traffic Jam

I've just had a mail from spaceports.com, who host my website, saying it has been closed down for the rest of the month because I have had o much traffic I've exceeded my bandwidth limit. I am perplexed - this is an obscure site on philosophy and linguistics that generally gets about two visitors per month. Either I've been slashdotted, or some search engine has misclassified me as a porn site.
