Theft of
Services
Spammers will use many tricks in their effort to "ply their wares". One of
the most common is to use someone else's email address as their return
address. Another is to link to images contained in their email, which are
on your web site, illegally using your bandwidth.
Using a stolen email address as their return address, is becoming quite
common, as some Internet Service Providers are checking to ensure that the
sending address is valid before relaying the message. They have started
doing this due to the " raft of complaints" received about mail going out
with a phony return address.
The consequences of this can be quite far reaching for the person whose
address has been stolen. This happened to me late last year. It was a
porno ad that was sent out bearing my return address. I got over 7,000
requests to remove their name from my mailing list in a 3 day period. Many
were quite nasty, threatening all sorts of things. I called "At Home", who
provides my cable service, to see if there was anything I could do about
it. Their advice was to use a different email address.
Fortunately
it was an address that I don't use for business, and if it was, it would
have been far more serious. The real problem here is not that your ISP
will shut you down for spamming, as it is fairly simple to find out that
you didn't send it, regardless of the return address.
There are three potential problems however, that you may have to deal
with.
The first is the number of "bounces" (bad email addresses that cannot be
delivered). Many ISP's program their servers to shut down an email account
that is getting a large number of bounces, as it is one of the symptoms of
a denial of service attack. If your bounces exceed a certain number -
usually around 500, your web server may automatically go into a "self
protect" mode and shut down your email address.
If you start receiving many bounce notifications, immediately notify your
ISP of the problem, telling them that someone has illegally used your
return address. If it was an email address that you use for business, the
bad press that you get can be devastating. You should write a short email
explaining what had happened, and send it to everyone who sends you a
complaint. While this sounds like a Herculean Task if you are getting
thousands, you can use an email package such as Eudora to do this
automatically. You can down load this software from our web site at:

Another
problem is that you can be quite sure that someone will report you to
"Spam Cop", who in turn places a complaint with your ISP. Spam Cop may not
check the validity of a complaint prior to notifying your ISP, which I
feel is unconscionable on their part. Unfortunately, if they do forward
the complaint to your ISP, you will have to defend yourself. That is why
you should immediately notify your ISP if this happens. If you have a copy
of the spam, be sure to send it along with your notification, and also
save a copy in case it is needed later.
The second major problem a spammer can cause, is to steal an image from
your web site that they use in their email. If they send their email in
HTML format, and many do, they can actually link to an image on your web
site. They are in effect stealing your bandwidth. Many web servers have
bandwidth limits, which limit the amount of information you can send and
receive each month. If you exceed that limit, you could be liable for
additional charges from your web space provider.
If they do this to you, your only recourse is to change the name of the
image, displayed on your web site that they are stealing. Another
effective step is to replace the original image that they are using.
Replace it with a notification that the sender of the email has stolen the
image from you, and advise anyone who receives it not to do business with
them. Once you do this, anyone who receives their spam will receive your
warning.
When you get
down to the bottom line, even people who send out emails with forged
addresses are stealing. If you receive hundreds of spam emails a day with
no way to have your name removed from their list, they are using your
resources without your permission. You then have to sort through all this
"junk mail" to find your legitimate email.
Theft of services is a serious problem. Unfortunately, it appears that the
only solution will be through legislation making it illegal, and provide
severe punishments for the guilty parties.
