Expose Trolling
So 9 days ago I had a troll in my ARAM game playing Anivia and sabotaging our team on purpose. He went W-W-Q into maxing W from the beginning, fired his Q on his teammates and instantly walling them off into the enemy every time one of us took one step too much away from our turret. He didn't attack minions for the majority of the game and pretty much ignored the enemies outside of flashing into 1v5 two times while managing to get 1 kill and 2 assists from them towerdiving us. He said something along the lines: "funny game :)" but nothing else.
The best thing about that game was that my whole team stayed pretty cool. We informed the enemy team "if you didn't notice, anivia is sabotaging our team on purpose" and told him that "trolling is a punishable offense". Surprisingly nobody flamed or harrassed him. On of our opponents was just so pleased that he tried to encourage Anivia to continue doing so and maybe even trying to provoke us (without success).
We reported him after the game and I also send in a support ticket, providing my replay just in case the support specialist didn't have access to it. They said they were going to look into the case.
Sadly, the troll is still playing the game, so the support has decided that the player was not trolling. Giving chat restrictions for sabotaging doesn't make sense so a 14day ban is the only thing possible (if not permanent) but that didn't happen so it is pretty much proven that Riot support acted against a team who stayed cool despite being trolled but instead backed the troll and encouraged him to continue.
It's really sad that support does not have the ressources or tools to look into replays because that's pretty much 100% proving trolling outside of chat. All this is sad. But out of all I pity everyone who's being trolled in ranked games. One game of ARAM is only one game of ARAM and nothing more. But having one's ranked progress spoiled is much worse.
Dear trolls, you can keep up, you're not going to be caught unless you're totally incompetent at hiding your actions.
