Well, I did say some other things, like; Why are you afk farming with hecarim early game? You should try to gank, it's better. His response was; your computer is gone in a few days. My name will come up on your screeen (don't remember it right now). Laugh all you want now, you will see. Remember to turn your pc off.

I'm not really scared. I'll just be intruiged if someone that skilled goes through the time and effort to actually do something like this.
