Getting spammed by the legit

Just when I thought that anti-spam engines were doing a great job weeding out those obviously detestable spam peddling medication, and fake watches, good legitimate marketeers take their place and get past the trusted filters.

As you can see in the below screen capture, I've put up with mumtazz.com for a while, not that I subscribed to it in the first place, but even after I unsubscribed the weekly alerts still kept coming.

According to IDA:
Under the Act, marketers - particularly those based in Singapore or who have operations here - who continue to spam the "not interested" group face potential financial penalties. The statutory penalty is $25 for each electronic message, up to a total of $1 million.
I believe under the bill, I am safely considered "not interested".

I guess where technology can't stop the spammers, legislation can help. Anyone else in the same spam list want to do something about mumtazz?
