John's correct. The huge increase in hitrate is observed *after* I report; I generally do a razor-check immediately prior to reporting for comparison purposes. Generally speaking, there *is* a slight increase in razor-detected spam between initial reception and my pre- reporting razor-check, but it's nothing compared to what I see after I've reported. Even after a week, during which I might have expected *lots* of people to report, the pre- and post-reporting checks are dramatically different. It just seems odd to me that my individual reporting could make such a difference! I guess I don't really understand the algorithm by which an individual message's spam-threshold-according-to-razor is determined. I should probably consult some documentation and see if I can get a better handle on it. :-) One possibility that occurred to me is that a greater proportion of the spam being sent out nowadays is randomized for each recipient. I don't mean the content the spammer wants you to read--I'm talking about all the fake HTML tags and bayes poison sprinkled throughout many messages. If the messages *are* unique (or close to it) then presumably my reporting a message body which is unique to me (or say, ten recipients) won't actually have a big impact for other razor users. ---- Nels Lindquist <*> Information Systems Manager Morningstar Air Express Inc. ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
