set up a filter in email to block the domain, report it as spam, report it to the ftc.

Spam | OnGuard Online

simply put it in your spam filter and thats it..

You could try SpamCop.net - Beware of cheap imitations they will help you report the spam to the hosting companies involved.

Or you could use gmail to collect your mail, they have excellent filters.

I just place these in my spam account also, because I am getting so fed up of wasting time unsubscribing and then it doesn't work like you say, so now far easier and quicker to click on the spam button and in the future it is them wasting their time and not you wasting yours!

Now you mention it yes I did notice an email from that address but it was in my spam and I paid little attention to it.
