This type of scheme is not new, it's been used by Prodigy and AOL before to 
get even more info. or profiles about users.

If you don't want to get profiled, don't surf the net.  If you don't want to 
get spammed, don't post to newsgroups.  There is no such thing as being 
anonymous on the net.

Hi all,

This showed up in my mail yesterday and thought you might want to see it. I
checked my cookie and found nothing from them - read on....

the

<www.doubleclick.net>

don't

entire

the

>| 
>| So what's happening is, subscribers to the doubleclick service put a 
"cookie
>| request" on their home page FOR THE DOUBLECLICK COOKIE.  When you hit 
such a
>| site, it requests the cookie and take a look to see who you are, and any
>| other information in your cookie file.  It then sends a request to
>| "doubleclick" with your ID, requesting all available marketing 
information
>| about you.  (They're very coy about where this information comes from, 
but it

>| "doubleclick" enabled sites.)  You then receive specially targetted 
marketing
>| banners from the site.  In other words, if Helmut Newton and I log on to
>| the same site at the exact same time, I'll see ads for wetsuits and
>| basketballs, and Helmut will see ads for cameras.

of

dough.

(Despite

>| 
>| Oh, and one other thing.  If you edit your cookie file BEFORE you connect 
to
>| "doubleclick," and then jump around at the site, you'll notice that they
>| DON'T hand you a cookie.  I probed the site pretty carefully, checking 
the
>| MagiCookie file, and nothing happened.
>| 
>| Until I closed Netscape.  The LAST thing the 'doubleclick" site did 
was....
>| You guesed it.  They handed me a cookie.  So much for making the
