Hacking/Cracking/ whatever a child pornsite is a waste of time. Even if you do take root access on the box, and you do rm -rf * then what? Any pr0n site (child or otherwise) has backups someplace. Whoo you took it down. So he goes, grabs a new domain, and right back at it again. So all you did was cost the guy $100 to put up a new domain basically.
Using the legal system may take 2 or 3 weeks, maybe even a month. But it would be a lot better to leave the site for a month and have the person arrested for 20 years then it would be to hack the site and have it back 2 days later.
