Anyway, out of pure curiosity, I went to see if the website killwithme.com actually existed. Apparently it does. Not surprisingly, it belongs to the maker of the movie. When you enter, it asks you for your name and such, and it enters you into a game. The object of the game is to solve puzzles so you can get clues to the login and password for the killer's server. It also times you while you're doing this. These puzzles are not hard at all, I am generally terrible at puzzles, especially while being timed, and I managed to solve these. But I won't ruin it for you. After it's all done, it takes you to a very interesting screen. Below, I will include a picture of the screen. I would love to know what it's supposed to mean.
Edit: I Googled the phrase "BHO the Illuminati" and got this YouTube video.
I also looked up "Illuminati" and found the following definition on Wikipedia:
"Illuminati is a name that refers to several groups, both real and fictitious. Historically, it refers specifically to the Bavarian Illuminati, an Enlightenment era secret society founded in the late eighteenth century. However, in modern times it refers to a purported conspiratorial organization which acts as a shadowy power behind the throne, allegedly controlling world affairs through present day governments and corporations, usually as a modern incarnation or continuation of the Bavarian Illuminati. In this context, Illuminati is often used in reference to a New World Order (NWO). Many conspiracy theorists believe the Illuminati, or the "Illuminated ones", are the masterminds behind events that will lead to the establishment of such a New World Order. Confusing the issue further is the fact that there are also several modern fraternal groups which include the word "Illuminati" in their names.
In rarer cases, the Illuminati refers to an elite set of enlightened individuals who may not cooperate but are uniquely empowered by their enlightenment, much like the intelligentsia classes of today are empowered by their education and intelligence. These are people who have become illuminated and have achieved a higher mystical understanding of the universe. Many secret societies and mystical traditions are concerned with this kind of illumination or enlightenment, such as the Rosicrucian Societies, the Martinists and the original Bavarian Illuminati."
It makes sense if you think about it. But I still don't know who or what BHO is. That could be anyone/anything, considering acronyms are not particularly specific. But judging from that YouTube video (too specific to be a coincidence, I think), BHO = Barack Hussein Obama, aka one of the democratic party candidates for the upcoming US election. Apparently the creators of the Untraceable site have a political agenda? But it was suggested on one site I looked at that the leaderboards were possibly hacked.
