Getting Punished

So, I recently played a game of karma support, (I am on holiday, and the network is kinda bad here) I got disconnected because of the network, I came back in 4 minutes, then I continued the game with no problems, we won, then after I honored someone, A message popped out that Leaverbuster punished me for 5 low priority matches, how can this be? I wasn't dc'ed the whole match, I do not like this leaverbuster anymore
