You know, I used to use "net send" to annoy other members of the tech architecture team when we were bored. A batch file makes it nearly impossible to get anything done, which in the right environment will start a nasty rubber band war. But I never extended it to spam.
The question is, how long before some ad service decides to take advantage of this?
In other weird news, a mall in Georgia has taken the pop-up ads and started using it in the mall. People pop up and annoy you to buy their stuff.
Now we just need to invent a pop-up people blocker that won't land you in prison.
