Hackers out there on PC?

I ask this genuinely because I've gotten a couple of very suspect matches. Input-perfect blocking even with mix-ups and 100% escape from grabs even during their attacks. But on offense? Straight gimmicks. Exactly one combo that rarely landed. I guess they figure to win by not getting hit?

Now I'm no pro, but I've had enough proper ass-beatings to know a really good player when I see one: guys with 30+ win Streak cruisining through Purple rank. They also do really good blocks but it's never 100%.
