Can you tell the Difference? A$$ clowns vs the Unskilled. Automate cancer killer!

Can you tell the difference from in or even post game stats who is a feeder or a troll? I think I can. There are few instances where I have teetered. For the most part i think something should happen to you if you are so bad people start thinking you are trolling and deliberately feeding. Something corrective. Trolls seem like the cancer of the community so I don't personally believe a prisoner island is a bad thing. We cut out cancer. We don't try and turn it back into what it was. Sometimes there is no going back, though it is a nice sentiment. What would you do in RIOT's shoes? If you can tell the difference. Can they automate some system that catches feeders and trolls and do something besides a prisoner island?
