Queue Suggestion, Feedback Appreciated

Sometimes, not often, but occasionally, comma, I see a series of individuals decline a match. Five or six times in a row. I'm not accusing anyone of anything, but could we possibly make it that if the same player declines a match three times in a row within a 60 or 120 second time span that they get a 5 minute cooldown on matchmaking? I only suggest this as a way to continue to improve game experience and prevent any kind of trolling from the small number of players who engage in this behavior.
