No Breath?

Hello CF players. Earlier yesterday, I was playing ghost mode as a ghost and I realized that one of my teamates had no breath. To double check, whenever I died, I viewed this person's screen. Usually you are able to hear the breath very loudly, but I couldn't. Walking near them in-game didn't make noise either. It was funny cause this player had like 30-2 after the first few rounds. Is there really a no breath hack?

Edit: I don't understand why people are saying my font is small; It looks just the right size to me.
