Time wasted on spam...
 

I must waste at least an hour deleting spam messages daily. To think I could have almost another 7 hrs/week for work but instead i'm picking through garbage.

Spam and the latest virus filling up my inbox. i get bored and just delete all my emails when its bad (i lose some pretty important stuff sometimes though :( )

Multiply that by the amount of people on the net and you get some daunting numbers of wasted time and loss of productivity for employers. Probably in the tens of billions of dollars per year now.
