But they have to work harder to do it. If spammers do as you say to "get around" TMDA, the user simply blacklists them with the first spam to get through. So spam, if not eliminated, is cut down, but the work of the spammer goes up. Of course, you could also do things to prevent auto-confirmers from working (like random confirmation messages and rotating confirm email addresses), but then the regular people can't hide TMDA behind an auto-confirmer either. -- David Masterson David DOT Masterson AT synopsys DOT com Sr. R&D Engineer Synopsys, Inc.
