I've had someone in games back to back... I specifically don't queue up for a bit after just to avoid getting in with that person again.. and it happens anyways.. especially when you start moving up the ranked ladder.
There should be no restriction. This person screwed up in 1 game, and screwed up in the next with a whole different set of people + you. No reason for you not being able to report him again.... If he's truly deserving of it chances are tons of people in your game will report him as well.
