Riot, Seriously, Deal with this type of behavior (Vent Incoming)

Posting in "Player Behavior" because it is the only place I can see it possibly fitting in.

I do not get how stuff like this keeps getting by. This is not the first time I encountered something like this in post-game lobby, and even after reporting people it does not get resolved. Unfortunately I did not get a screenshot because I was honestly just overcome with irritation and frustration. (Picture attached of after game score screen).

I get that some people get toxic and talk trash which is whatever; I get over it and move on. This post-game chat got to me though. Let me set this up:

Pre-game I do my typical thing, look into each of the enemies. Some high-tier silvers with a platinum 5 ADC? Damn. Got the game difficult set up for me. Well I am having fun, having a good night, and decide "I haven't played Xayah in a bit, why not?" (For reference, I'm a Gold 4 bot lane main). Myself, my support thresh, mid-lane talon, top lane tryndamere and jungle nunu against a bot lane ezreal and Alistar with a top-lane garen, mid-lane kassadin and jungle hecarim. Playing with friends, having a great time, taking trades, a typical game. I am DESTROYING as Xayah, 9/0/8 by 20min, going legendary twice and ending the game at 15/3/15. Just doing my thing, trying to have fun. About 33min in there is a massive team fight under the tower. I decide to start pushing the minion wave, I mean, we need them to keep going right? Sure, they have two open inhibitors, but death timers are long. I have my support me with me while my jungle decides to suddenly run up and try to take the inhibitor. The enemy jungle comes out of nowhere, outplays Thresh flay by using his ult, and kills me. I simply tell the Nunu "Hey, you cost us the game by going for the inhibitor", and I mean yeah, I'm a bit upset, but I would have gotten over it.

Post-game lobby though I get verbally destroyed by not only our jungle but 3 out of 5 members of the enemy team. Nunu instantly starting off with how mad I apparently am. Between the enem, ADC deciding to tell me " Xayah. You suck." Ok, whatever, my CS was pretty bad, fair enough. I don't play Xayah a ton. Alistar chimes in instantly and starts saying random things such "Hey Thicc, do you dress up as a dog and go woof woof?" Kassadin deciding to pipe in with "You seriously suck, you can't even orbwalk" Which I say "Yes, I did." To only receive, in response, "AHAHAHAHA! N***** NO YOU DID NOT!" and proceeded to continuously get told how bad I was and how my poor team fighting choices were why we lost. The only two that did not say anything on the enemy team were the garen and hecarim.

I ended up just reporting, but something tells me nothing will be done (unfortunately). I have seen things like this to other players and it is despicable how this keeps going on. I had a friend that stopped playing because they encountered this type of behavior in a post-game lobby and decided that this game was not worth playing in any sense. Riot, please, deal with this type of behavior more often, and with something more than a slap on the wrist.

Sincerely,

Just an average gamer.
