The Operator Symbol is connected to the ARG, not to Slender Man. If you're saying the truth, someones playing foul on you. someone who did not do his homework right. Also, you should see a doctor. Coughing blood is not healthy.
About Slender Man, could you describe what he looked like?
Hey im a girl and i actully to be truthful here i did do my homework because if you watch marble hornets the operator symbol is used for slenderman
There is no SlenderMan in Marble Hornets. Your homework is incomplete. The fact that you're a girl doesn't make you honest.
But I think I'm supposed to be the nice guy here, so let's say you're right:
According to some theories, Slender Man manifests due to human psyches. If many people, who did not make their homeworks, associate Slender Man with the Operator Symbol, it could actually connect to him in some way. It bundles the believe. However, most likely Slender Man is not aware of the very symbols. If the Symbol is really connected to him, someone else caused it to appear, a fanatic, maybe. About the static, that's just not how it works. I still think you're a liar, but let's say it was an suggestive effect, yes? Nose bleed, blackouts and insomnia might be caused by nervosity, since you feel stalked. The question is, did you really see Slender Man? If you're paranoid because of the mythos, you could hallucinate easily. Happened to me.
Marble Hornets is 100% fiction, and Slenderman is not in there...The Operator, a character loosely BASED ON Slenderman is.
OMG, Luffy iz Slendah!*
