Instalocking

Please RIOT why dont you punish ppl for instalocking and leaving games, you have to fix this. For the last three games i've played someone instalocked and took my role and i have to play whats left. Shouldnt I atleast get a reward for being sportsmanlike. And why is there even a report button anyway, like my reports doesnt even matter. I just want you to fix so ppl dont instalock or dare to, like give it some punishment for instalockers and reward ppl that are nice and calmly accepts that they have to get another role wich they do not prefer. And dont say like "its up to the comunity" or "we cant handle it its to big of a problem". Fix it, give them a hard punishment to scare them of from doing it.
