Does the tribunal or reporting actually do anything?

I'm starting to think the only way someone can get even a temporary ban anymore is to blatantly piss literally everyone off in a game. The last game I played the adc openly admitted he was a first timer with him. Ok, fine, so I babysat him, made sure he didn't feed. Then he starts afking and when he comes back he apologizes because while he's afk he's getting drunk and vomiting. These are norms and I'm expecting this some of the time but thats almost all I've seen this evening and these brazen turds are only becoming more numerous and regularly found over time.

I said all that to vent honestly but I just wanted to ask others if there really are players or anyone at all doing this tribunal or if it even exists. More and more often I find players who as far as i can tell are there just to troll, meaning they regularly afk, refuse to group (if anyone even groups at all), or are just plain toxic in one way or another. The whole point of having a reporting system i thought was to keep this sort of stuff in check but since I've seen even more of this either the tribunal is some made up bull riot cooked up to make players believe those people are getting their warnings and bans (temporary or permanent), the system itself is uselessly obsolete, or anyone who just wants to play as the game was meant to has already left to play something else. The last I'm betting is most likely since I, my friends, and random players will say they spend little to no time on lol anymore. I know I've basically walked away from it for a few months at a time (save jumping on to knock out a daily on bots) simply because those who are playing for fun and actually trying to win have become so few and far between.
