OMG I WAS IN PENNSYLVANIA VISITING FAMILY I SWEAR!!!1one

Or at least that would have been my excuse if I was a "top player."

Awesome, I hope they keep this up.  This is the exact reason why a 3 week delayed ban is fantastic.

haha, that's funny.

VAC only manages to catch stupid hackers who are using outdated exploits.

If you are smart about your hacking, it's close to impossible to get caught.

Why doesn't VAC try harder?

[Labyrinthine]

Because then they would turn in to blizzard and would watch what processes are running/what is open in your web browsers while you're running the game via a program similar to warden.
