The abhorrence of anonyminity by those of us who live in, or come from, a rural society (or an academic society) is palpable. One who tries to hide must have a nefarious reason to do so. SPAM avoidance is a make-weight reason. ... my opinion. Mac N8TT I get huge amounts of spam at this address, but it is because it has the dread initial/number/domain combo, not because I post to newsgroups with my real name. The spammers simply send out mail with a gazillion combinations of initials/numbers/domains, and hope something hits. In my other address, I post with real address and name too, and get very little spam. I wonder just how much newsgroup harvesting is doen these days. It wouldn't be very efficient. - 73 de Mike N3LI - |

Hi Mike
Well if I was creating a databases of addresses to SPAM (shudder!) I would add on an SMTP engine that tries to connect to the host. If I got a "550 mailbox not found" or something similar I wouldn't ever bother trying again. It would be fairly easy then to have a known vs invalid addresses. That along with (say) grabbing names from telephone books and creating addresses with it for every domain that could be found would build up a credible database to work with. Once the engine is perfected a 95% failure rate is still a success.. I am sure there are institutions around that do this, if just to sell a useful database to their customers. There are however far better and more slimy programmers around than me! I would suspect (but don't know) that ISP SPAM mitigation processes are helping a lot nowadays. There have also been laws passed and ISP acceptable use policies that are making things a little bit harder for the SPAM creators... Most mail servers also have a lot of lookup/checks that go on nowadays when they receive a connection. I think about half at the place I work fail to connect because they are requesting relay, have an invalid source domain/reverse lookup or something else that prevents the chaff getting through. Those that do then have the SPAM pattern filter trounce about 95% of. Cheers Bob VK2YQA Michael Coslo wrote: I wonder just how much newsgroup harvesting is doen these days.
