3 Reboot all done facebook is now blocked this can be undone by deleting the list out of host file

For the network people out there this can be pushed across a network as a policy as the hosts file can be built into a script when a user logs onto the domain it downloads it from a file server.

You can add any site to the list with a redirect to the 127 ip. better then a child protection software solution.
