Hijacked totally illegal, You can contact the FEDS and they can check it out, I've seen some website hijacked or hacked sites.

I remmy surfed to my old webbased email and saw "Happy Halloween Hack", I hit the A/C/D to abort the IE browser and disconnecting a modem. I called the company for reporting website hacked, I told them better call up the FEDS, they shutted down the site for awhile. a few days later they finally caught a hacker.
