Dam leavbuster

Like you gotta be kidding me right now, I just played a game, had my internet crash and so I afk'ed for about 5 mins, I did everything in my power to get back within the 5 min marker, my teammates didn't mind and even helped me get some cs and gold and we won the game anyways. Why the hell did I get leavebuster, i'm putting this in report a bug because if this piece of crap system is in this game on purpose than i'm a stop playing.
