Hello Sniffer folks, Just in case you've been watching, the last few days have seen a large number of new rules... However, this time, it's not a spam storm.
(From Rule Base Change Rate Analysis> <http://www.sortmonster.com/MessageSniffer/Performance/ChangeRates.jsp> Days Ago Adjustments -------- ----------- 0 1322 1 2509 2 381 3 494 We have been experimenting with some new robots with improved intelligence. These robots help us to generate new rules automatically so that we can respond very quickly to new spam. They are getting very smart, but we always review the rules they create manually in order to maintain their quality. During the last 15 hours or so, we've been running a "deep scan" experiment that allows us to capture additional rules that might exist in spam we've already filtered out. While tuning the robots to perform deep scans we've allowed them to run "wide open" and in the process we discovered that they can be quite prolific. While we continue our tuning process we're going to see some unusual numbers in the Rule Base Change Rate analysis. We should be done with this work in the next few days. After that things will settle down and look more "steady". The new robots have already had a very positive effect on our capture rates. The combination of changes we've implemented over the past six weeks has significantly increased Message Sniffer's accuracy in all rule groups - driving false positives to record lows and capture rates to record highs. We expect to see these trends continue over time as our robots and SPHUD tools become smarter. (SPHUD = SPam Heads Up Display: This is a tool we use to research new spam that arrives at our system through spamtraps and user submissions.) A good place to see the effects of our work is on the Spam Test Quality Analysis page by Markus Gufler: <http://www2.spamchk.com/public.html> I hope you find this information to be both useful and interesting.
