Nope.  It's obvious when someone is hacking.  This guy was definitely hacking.  Him and the other Ai guy.   I was dominating the match.  Easily killing both of them, along with everyone else.  I got a pavelow.  Then the screen froze after it got 3 or 4 kills.  We went back into the lobby.  Then back to the same map with the same teams, but they had their hacks turned on.  When I suspected they were now hacking I went to my assasin pro and ninja pro class to confirm. Ninja pro rules out your soundwhore theory.  There were several situations where it was impossible that they knew where I was but still prefired well before they could ever see me. (i'm not getting into details, but again, it's obvious when someone hacks)  They were both using red box and akimbo.  There was no portable radar laying around either.  I checked for that first with sitrep pro before I went to my ninja pro class.   How would you know he is 100% legit anyway?  Do you go to his house and watch all of his matches?  No you don't.  You assume he is legit.  If that was him, he's not.
