A bit overactive don't you think? Hacking is against the law, and if a case comes when a hacker does manage to find a loophole, every little move he makes is being watched by the authorities. Best chances are to just leave this stuff alone, if there's someone downloading childporn or have a history of it, let the isp's monitor it and report. It's more their job than anyone elses (say someone who was downloading the kiddy porn to find out in the first place?). 9/10 cases, you'll be caught for something too, so it's better to play it safe.
