Ah hobo, I feel for you. n game 1 you got trolled so hard by those 4 that qued together lol. League probably has one of the most sensitive player base I've ever seen haha. I remember when I was a dota mod and had cases we actually looked at replays and chat logs to base our decisions. There was also a threshold for bad attitude/spamming/verbal abuse. For instance noob, bg, etc is a silly thing to get banned for.
What made the TDA system really work was that people HAD to save the replay, then HAD to log on and post the replay with reason, time, etc. Because it took effort to report people we only really got decent reports. Sure some were stupid but most reports were genuine. Here, you can just report someone for bg if 4 of you are que'd together *cough cough game 1 cough* with a simple click and this silliness happens! Hell I bet those 4 players never gave you a second thought :P
Also people were really scared because we banned IPs not just accounts! So no more smurfing from those people banned.
Btw I didn't look at the other games just because I wanted to reply about game 1. So ya... good luck bro! Hope you don't say noob, bg, or any other taboo word! I personally only communicate with pings cuz I'm a rager
