And a Bayesian spam filter requires a body of marked 'non-spam' as well as 'spam', so it only works at the client side; another good reason to do the filtering yourself, not on the list. (That is, unless someone is going to volunteer to mark each ruby-talk message as 'spam' or 'non-spam' - a sort of post-mortem moderator. But their efforts would give such a minimal benefit to the community that I don't think it's worth it. The amount of spam I receive from sources other than ruby-talk is at least 100 times higher) I would not like to see any static rules-based filters on ruby-talk: they have too many false positives, and every time a false negative occurs it will start a thread saying "why don't we update the filter set to match XXXX ..." which IMO is worse than the spam itself :-) Anyone who hates spam can apply their own filters, and they will have the benefit of trapping spam from other sources as well. Actually, since I thought ruby-talk is gatewayed to/from Usenet, it seems strange that we get so little spam here? Regards, Brian.
