Unfair chat bans and punishments

So today I received a 1 game chat ban, which is of course nothing much. But i'm upset about this because of why i received it. The previous game(s) I played I did not flame, however, I was reported by someone who I beat in lane because he was lost his lane and decided to cry. From this I got a chat ban... Is it because of the new tribunal system? or.... Anyone else experience similar things? Do the reports get monitored less? Do the punishments are issued more from false reports? Not very fair imo
