oh yeah -- good point. On one occasion in the past when spammers have evaded open-source-developed rules, I was able to find out later why they made those changes, and it had nothing to do with our little open source projects... instead it was to evade AOL's independently-developed, closed-source, secret-sauce filtering which used a similar method. The big guys are the spammers' targets. --j.
