Beating the Tribunal bot.
So I just watched an ADC go AFK for about a minute over 6 creeps that the top lane took in lane. Not a weird story in itself right?
Next he comes back and starts wandering to just short each tower. Never fighting, occasionally killing creeps but staying way out of range of fights or enemies. We end up getting pushed back to base towers. The enemy didn't see him for a while so they agreed to report him AFK.
This is where it gets annoying. He spends the rest of the game ulting every time it's off cool-down into nothing but occasionally hitting the enemy with 1/4 shots. He throws out CD's every time they're up (at nothing), and starts being remarkably nice in chat. No one believes him and everyone on both teams is basically silent.
Then I realized he was trying to beat the AFK buster and Tribunal bot. So I asked everyone to say that they saw him being like this. Everyone was silent but him, he was playing the victim now. Silence from the team. After game everyone reports him. All 9. No message about catching a toxic player. I'm pretty sure he just beat the Buster and Tribunal.
I don't know if the report system can beat this kind of trolling but I hope this helps.
