Get Even! In a 24 hour period
starting at 10: A.M. this past Tuesday, and ending at the
same time on Wednesday, I received 1,734 pieces of spam
email. Now these were all unique addresses,and some had
4 or 5 copies.
I have had it with this nonsense. Looking at the email
addresses, it was obvious that mine were being harvested
from the web.
There is software, similar to the protocol used by the
search engines, that allows someone to enter keywords, and
it will search the web for any web site that matches the
keywords entered. It will then capture any email addresses
it finds. An example of such software is "Atomic Harvester".
I downloaded this software, which is fully functional in
its search capabilities, and is free if that is all you
want. You cannot however, save the addresses it finds unless
you pay for it. Not wishing to harvest any addresses from
the web, I chose the free version, as step one of my devious
plan, so I could see what the spamsters would find when
they harvest my site.
Step two was a bit more work. Instead of simply deleting
the spam, I created a filter with my email reader that automatically
sends all spam identified to my trash bin. I use Eudora,
which makes this a rather easy task, but was still time
consuming. While this won't provide a "spam free"
inbox, it will cut down on the junk one has to wade through.
The rest I simply delete, which also goes to the trash bin.
Now, I have all this spam in once place - my trash bin.
But wait, I said get even. A good friend of mine is proficient
in the "Perl" programming language. He wrote a
program that goes into my trash bin, and extracts all of
the "From" email addresses it finds. Now I have
a file of all the return addresses of anyone who sends me
spam.
The majority of the professional spammers use a forged
address, which if you respond to it, is returned as undeliverable.
Some of the naïve newbies use a legitimate address.
I then put all of the addresses in a file on a web page
with an invisible link to it - let's call it the "Trash
Page". If you visit my site, you will never see it.
But, a spammer using harvesting software will hit that page.
They will harvest each and every address that I loaded onto
that page.
Thinking they hit a bonanza, all those unduplicated addresses
will be captured by them. Now, two things will happen. First,
all the forged addresses on the list that they send to,
will be returned to them as undeliverable, causing them
extra work to clean their lists.
Second, all the spam received from a legitimate address,
will be on the lists of all the spamsters, and they will
get their "just deserts".
Eventually, the pros will figure out what I have done,
and will block the web page that houses them. But that is
not my goal. I started putting those invisible links to
that "Trash Page", on a number of my web pages.
Now, they can't just block a particular page, but will have
to block my entire domain. Great - now I won't have all
the addresses on my site being harvested by these miscreants.
If this idea snowballs, and I hope it does, a major percentage
of all the email addresses being sold by "email list
providers" will be worthless. You might think about
this if you are ever tempted to purchase their "thousands
of email addresses" for $49.95.
The spam problem is not going to go away in the foreseeable
future. If webmasters took the steps I have taken, it just
might go away sooner. Anyone who sends me an unsolicited
email, advertising their "latest and greatest, will
wind up on this list. |
