From Dominic Jackson
Bruce Schechter’s report neglects one important point. To apply Bayesian filters one must first accept the entire spam message. Given the ever-increasing size of spams as the senders resort to HTML formatting and other tricks, this places an ever-increasing burden, in terms of bandwidth and disc space, on ISP mail servers. Blocking all emails from open relays — or blacklisting, which is compared to terrorism in your article—does not suffer this problem.
