Why would you want to give feedback to the spammer? Anyway, it seems to me that real spammers are getting more successful, not less successful. They have won in court, and the radicals on spam-l have given up on lawful methods. And it also seems that real spammers have T3s, opt-in lists, working opt-out addresses, and tend to be fairly responsible, so far as I can tell. They are clearly not the ones sending out the garbage that is most annoying---most of that isn't genuinely commercial, or even genuinely fraudulent. (To commit fraud, you have to take money). For example, none of the Nigerian scam mails that I've responded to try to get information or money, nor responded at all, except for one person who said his address was forged. Indeed, the DMA (Direct Mail Association), a historical advocate of junk mail, and also of spam, has taken the position, essentially, that legal controls are necessary; Not on genuine spam, but on the abusers sending garbage to annoy people. In other words, the radical antispammers. --Dean On Mon, 15 Sep 2003, Iljitsch van Beijnum wrote: > On maandag, sep 15, 2003, at 03:50 Europe/Amsterdam, Dean Anderson > wrote: > > > I think that content analysis holds much promise.
