At that point they may already be senseless, but you beat them up anyway.
Side note, since you combined "in fact" into one word and I read the post very quickly, my brain initially read it as "can you infract someone who beats you senseless" at first. Can't imagine how that would go. Someone's beating you up, and you threaten them with an infraction on a message board if they don't stop. That'll show them!
...and I'd get infracted just for watching cheerfully...
