 The great referral spam wars continue...  At the last turn of the crank, I noted I was getting a bunch of bogus referral hits from URLs which are not on the air.  There doesn't seem to be any point to these, but still they are annoying.  So I changed my filter a bit to check whether the domain for a referer is registered in the whois database.  If not, I drop it silently.  I am back to taking a quiet satisfaction in my chaste referral logs :)
