The Ecological Impact of Spam

krou writes "A new study entitled 'The Carbon Footprint of Spam' (PDF) published by ICF International and commissioned by McAfee claims that spam uses around 33 billion kilowatt hours of energy annually, which is approximately enough to power 2.4 million US homes (or roughly 3.1 million cars) for a year. They calculated that the average CO2 emission for a spam email is around 0.3 grams. Interestingly, the majority of energy usage (around 80%) comes from users viewing and deleting spam, and searching for legitimate emails within spam filters. They also claim that 'An individual company can find that one fifth of the energy budget of its email system is wasted on spam.' One of the report's authors, Richi Jennings, writes on his blog that 'spam filtering actually saves an incredible amount of energy.' He continues, 'Imagine if every inbox were protected by a state-of-the-art spam filter. We could save about 75% of the spam energy used today — 25 TWh per year; that's like taking 2.3 million cars off the road.""

    Please stop responding to SPAM. If no one responds to it, then they won't make any money and they'll stop. Sincerely, A. Bettik

    Can you actually respond to them? I once got a spam email and I was in a really pissed off mood and wanted to take it out on someone who deserved it, so I tried to contact the spammer. The email they included didn't work. There wasn't any phone number. I couldn't find any way of contacting them. I can't believe some of those morons actually make any money. Sometimes, I wonder if it's the ISPs that host those assholes that are pushing this shit. Maybe convincing stupid people that they can get rich sending mass electronic marketing or some other made up buzz word that obfuscates the fact that they are selling you a spammer package. Moron spammer buys it, sends out a bunch of emails, and then gives up after a while; only to have another moron take his place? Just guessing.
