This site is perfectly safe; it is the site for Kali Linux, which comes with more than 300 preinstalled hacking tools (see Kali Linux on Wikipedia) however, children (or anyone) may abuse those powers and do some damage. Probably best with supervision.
Kali Linux is a Free Software operating system based on Debian GNU/Linux.
Kali is specifically tailored to meet the needs of penetration testers (see https://en.wikipedia.org/wiki/Penetration_test for a definition). As such, it contains all sorts of tools that are not suitable for children.
Other than that, Kali's website is perfectly safe to visit.

Great hacking distro!! however it dose not work out of the box.
Also kids should not use this unless they know how a computer works, the installation can ruin your comp if you put it on a used partion. It made me have to use hackintosh till i got windows. Not being in a inf. Grub boot loop.
