There are several viruses out there that pull names from NG addresses, and
then send them junk advertisements or use their address in a spoofed 'sent
from' field of an e-mail. Sometimes it isn't an advertisement, sometimes
it's a virus laden phony 'update' from Microsoft or some other official
sounding source. I get about 50 or so of these a day at an old e-mail
address I used to use.
There are also programs written to 'harvest' e-mail addresses from the NG's.
These are used by direct-to-your-PC marketing schmucks, sometimes referred
to as spammers. They will send out a hundred million e-mails in hopes that
0.1% of the people, who read the ad, will respond. If they do, then the
marketer gets rich. But, everyone else has to wade through the garbage
about enlargement, on-line mortgages, degrees without schooling, dating
services, 'special' friends that will being town and want to chat, drugs
from overseas and the like. In one estimate, the cost of the work time lost
to this (just deleting the bulk e-mails) was measured in the millions of
dollars every year.
There are some anti-junk e-mail programs out there that help to filter out
the unwanted e-mail before you ever get it. Some use white lists, some
black lists, some look for key words or capitalization/punctuation
percentages, some use community feedback, some use combinations of these.
There is even one (sorry, I don't remember the program name) that attacks
these spammers, by downloading 5-10 or more copies of the response web-page
and deleting them all. The idea is that, if everyone did this, the spammer
would be flooded with responses (that would make him use a lot of band-width
that he has to pay for). The web-pages are all deleted without being shown
or stored on your computer.
But the bottom line is this: By changing my e-mail address a little, it
sends the virus and spammer generated junk to a dummy address where I don't
have to delete it. If a real person wanted to e-mail me, they would read
the tag and know to change the domain of the address. Org to Com.
It is strongly recommended that all posters use some form of misdirection.
