New software won’t just protect you from hackers. It will fight back, though it isn’t clear exactly what form that will take.
This concept isn’t new. Years ago, failure to respect web-spidering etiquette by not paying attention to the robots.txt file of some educational institutions might get your site spammed by several megabytes of data.
The idea of fighting back via software is certainly not as harsh as killing the perpetrators, which has been suggested somewhat wryly by some. Based simply on the time I have personally spent to rid my own computers of these kind of problems something needs to be done, and soon.
