I had been getting a lot of spam in my mailboxes lately so I decided to do some proactive emailing of my own.

I went through my emails and when I saw a bunch that had the same unsubscribe link that goes to the same url across several websites I found the contact information for that company.  (adchemy and dnelist come to mind)

Being a follower of www.danhatesspam.com I had went to my state code and found the law governing unsolicited emails.  In Arkansas we can sue in small claims court for a penalty of $10 or $25000 (which ever is greater *insert sarcasm*) for EACH unsolicited email.

I wrote an email to each of these media advertising agencies that went something like this:

Hey,
 
I'm getting way too much spam from your clients.
 
What I need you to do is put my email on your blacklist as I NEVER want any information from ANY of your clients:
 
myemail@gmail.com
 
 
I will give you 7 days to clear this email out of your systems.  This also includes any email from your affiliates that is connected to your url.
 
After 7 days if I receive even one email from you I WILL be sending a notorized cease and desist order and begin court proceedings.
 
Arkansas Law allows $10/25000 PER email for spam.  I will create a folder and each time you spam me I will put your email in it's folder and when it reaches $200 in fines I'll trot down to the courthouse to file a suit.
 
I'm a huge fan of www.danhatesspam.com.
 
Thanks for your attention.
 
Jason

Would you believe that when I checked my email tonite I had absolutely NO spam.  It wont last I fear and I may have to follow through on the sending the notorized cease and desist but it was nice tonight to have no spam.

True but if you are consistently getting a lot of spam from the same company that you recognize when you goto their unsubscribe page find that companies main url and then their contact email. 

Easysolutions4you, Adchemy, Dnelist, were some of the ones that would send me multiple emails from different clients but use the same unsubscribe image for each email.
