(from the depressing milestone dept.)
Since January 16, 2006, over 940,000 attempts to post comment spam to this site have been logged. That’s 10,000 spam comments since August 25, 2013 and over 184 times the number of legitimate comments posted to this web site since June, 2001.
So.
This is clearly complete bollocks, you fail to state any criteria of how you tell spam from “legitimate comments” sadly all webmasters are arseholes
