What does it take to get banned for griefing/trolling/int feeding?
I quit over a year ago due to Riot's inability to deal with toxic players. Almost every game either has a troll on your team or on the enemy team. I started playing 2-3 weeks ago and the situation is exactly the same as a year ago. You can troll, grief and intentionally feed the entire game, as long as you don't say any forbidden words that gets you flagged you will get away with it. Last game I played with a Tristana adc. After 5 minutes he already decided the game was lost because 2 players had died so he decided to grief the rest of the game. He went top to troll, then jungle, refused to farm the rest of the game, bought support item and didn't do anything useful but moving etc so the system wouldn't flag him. I called him out a couple of times due to sheer frustration and all he said was :"Nothing will happen, I won't get banned because I am still playing". This guy is literally playing the system to not get banned. Its pathetic.
After the match I looked up his history. Out of 20 games he did the same thing in 9. So in 45% of his games this guy is trolling the hell out of his teammates ruining countless of games. I am sure he got reported at least 100x by now, so what does it take to get your account looked into or get flagged by the system and actually get banned for trolling, inting and griefing?
I am at the verge of uninstalling again because it seems Riot hasn't made any progress at all in dealing with toxic players who play around the ban system.
