Death Note online version is basically an anonymous guestbook. It works like the Death Note where you write the victim’s name, cause of death, and optional details of death. The only different(thank god!) is that the “victim” will not die instantly. It is only a joke site. Maybe you can use it to release your pressure/anger too.
