I am trying to do some reasearch on junk e-mail and spam e-mail.  In
order to effectivly research this topic, I have established three
different (and disposable) email accounts with my ISP.  My goal is to
have one of the three boxes inundated with junk mail.  In fact, I want
the amount to be staggering!

Can someone give me ideas for making this email address a target of
mass mailers, junk mailers, etc...  The method(s) need to be simple,
and I don't want to have to "confirm" any registrations.  I want the
resulting submissions to be silent and without warning.

Posting your email address in a popular Usenet group is a good start.

Posting your address on several american shopping sites will atract money market.
Also if you dare visit a lot of porn sites

Phil Bradley's Great Spam Experiment found that the most effective
method was to follow the unsubscribe procedure specified in some spam.

I'm not an official Researcher, so this can't count as an answer, but
I think the following website is exactly what you're looking for
(assumining the site is serious).

http://www.spamyousilly.com

Here's the info from the site:


What Do I Get From Spam You Silly!®? 
Within approximately 1 week of signing up with Spam You Silly!® you
should start receiving between 2,000 and 7,000 unsolicited emails
daily for as long as you remain a member!

How Does It Work? 
Step 1. Spam You Silly!® has compiled perhaps the largest list of
spammers on the planet, over 30,000 entries. Our automated systems
will send each spammer on this list your email address requesting
product information, a business solicitation or to be put on their
mailing list. Every six weeks we do it again as long as you remain a
member!.

Step 2. Spam You Silly!® will submit your email address to over 500
"hot lists". A hot list contains email addresses of people who have
purchased products on line and who are likely to do so again. Hot
lists are usually sold to solicitors at a premium to maximize spam
effectiveness. Spam You Silly!® puts the power of hot lists to work
for you!

Step 3. Spam You Silly!® utilizes "web bots" to crawl the web looking
for sites that offer products or services for sale. When one is found
that allows an email to be submitted for contact or further
solicitation Spam You Silly!® will submit each and every email address
in its database.
