Still, a dumb autoresponder is good enough to get round TMDA :-(
That is not the end of the world. As Jason has pointed out in documents, it is simple enough to extend TMDA to require a more intelligent response (i.e. from a real human). The question is how to get the most immunity from any conceivable autoresponder system while still making it easy for humans. One possibility is to attach a graphics file containing a word which must appear in the reply, perhaps with a background to confound any image recognition programs. Another is to ask a question requiring a specific response. The graphics file approach seems the most direct. One should not make the challenges too hard. For example, "please include the numerator of the irreducible rational with numerator and denominator not larger than 255 which is closest to 1.6093" might be a bit too hard. The answer, by the way, is 243. The number is 243/151. Dave. _____________________________________________ tmda-users mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-users
