Reported Player Cannot Queue With You Again

Just got out of a game in which my adc had a terrible attitude and berated us with expletives right at the end of the match. I died so many times being their meat shield and really did my best but our comp and tactics just weren't well put together. I reported this person after the game and entered queue again.... and there they were on champ select calling me garbage (among other things). I dodged the game after letting the rest of the team know that this person is highly toxic. So now I face a cooldown on queuing again and possible future penalties for simply avoiding players that I have reported. It doesn't make any sense to me.
