I vote that people feel that spam is offensive because it is an address that you chose(usually) & it feels like a personal means of communication.
As far as spam putting $$$ into the economy... cmon dude.. what planet are you from?
Spam generates BILLIONS of dollars in revenue every year... and it DOES cost them money to spam.
I don't want to come off as the spam protagonist here... but I do come home to a totally packed physical mailbox when i go on vacation... usually packed with credit card offers, coupons etc... I have no way of stopping them from filling my mailbox...and i assume that my neighbor probably got the same mail so i don't complain.
Maybe spammers would receive fewer complaints if they just prefaced the entire email with a "This is not personal. You are a consumer & I have something to sell. This is a mass email & you are receiving it simply because you are on the internet, not because you did something to get on my list. If you don't like my email, delete it. If you are angry about receiving unsolicited emails, stop turning on your computer. If you would like to live in a commercial free internet, the minute you just spent reading this email will have cost you $1.99.
Cheers,
