Got leaverbuster, screen goes black in champion select AFTER low priority

My game just crashed BECAUSE OF A BUGSPLAT so, i just accepted it because im used to getting leaverbuster due to crashes...So, i just went into a low priority queue, and after facing it, i went into champion select but my screen was completely black...Its unfair that we have to face punishments for glitches, right?but after all, riots punishment system is fair right?[slayer-jinx-unamused]
