Pretty sure I ran into a hacker

I was just playing a Hearthstone match against a guy named DAD. It seemed to be going fairly well. But we only got 4 or 5 turns in and suddenly the guy I’m playing decides to take an infinite turn.

It didn’t say I was disconnecting. It didn’t say he was either. And it never said he left. I sat there for several minutes waiting for his turn to end. I even walked away to talk to someone and came back a couple minutes later and the guy was still taking his infinite turn. I eventually just quit the game.

Please do something about this nonsense! It’s not the only time I’ve encountered people that seemed to do something sketchy. I’m finally tired of it though and I would like to see something done to protect people from this kind of thing.
