This is just a waste of effort and money... For every torrent site they mange to take down, two more will replace it. And even if torrent sites get phased out, something else will replace it.
Prevention is better than cure... and this is not a very good cure anyway.
Every profession has some form of hazard.
Computing/Programming/IT -> RSI
Barwork -> Risk of broken glass/drunken idiots
Basically what I'm getting at is, if you can't take the heat, get out of the fire.
