Disproportionate response to SPAM

Yesterday I invoked a ridiculously disproportionate response to a piece of SPAM.  No I don't want to buy a Renault and I don't appreciate not having an unsubscribe option either. This email must have been harvested by buying what is euphemistically called an opt-in list.So not only were there no unsubscribe instructions, but if you visited the Renault website, the only way to unsubscribe was to provide more information: name, address, phone number, email address and information about my current car.  All this to stop receiving rubbish!So my disproportionate response is a simple mail filter than trashes any email with the word renault ANYWHERE in the message & a greasemonkey script that removes Renault from any text rendered in Firefox. It's now not possible to send me an email with Renault anywhere in the message. In my internet world, Renault no longer exists.  Perhaps one day corporates will notice that sending marketing emails without explicit opt-in permission is a no-no!
