4Game

So I ran into a case where the player was normal (although getting false reported for feeding throughout a losing game, it ended like 15-50 or something, not actually feeding). But 3 minutes before the game ended the player sold his items (this part is bad), and hid in trees. They never moved their screen so they had just left I assume. At this time they were down a lane of barracks and 20k gold, he had a very bad game and had only a couple items at 30 minutes. Not an impossible game, but definitely a 99%er. His team took one last fight and killed 4 while losing everyone. Then they gave up and upon respawning the enemy team got megas and ancient.

I ended up saying insufficient evidence as I was honestly unsure. Did he give up pre-maturely? Ehhhhh, maybe. He didnt need to sell his items. I dont think what he did was malicious intent, he just believed the game lost as the enemies coulda just got mega creeps but did the archon pub classic of running around in enemy base. I rarely have done something similar, but only really when the enemy team has mega creeps already and our team is hopeless (flaming/bad-lategame/etc.), or I dont want to get farmed in fountain. Maybe he had to do something out of game and figured it was a loss.

What would you have done?
