iMedia: Spam is More Stressful than Traffic

A Yahoo study of 37,000 email users found that Americans fall into two categories: those that ignore spam and don't care much about it, and those who are very knowledgeable and active in thwarting it. Four out of five delete their spam, and more than half employ spam filters. A third of Americans respond to spam, some just to vent at spammers, but 20 percent to actually purchase products.
