No. *clicks punish*
If a player openly admits he's feeding, and/or if his death counter is absurdly high [i.e.: 1/23/3], then that would constitute "intentional feeding. I'd say if any player is about 15-20+ below in k/d/a ratios, then it's highly probable that it was indeed intentional.
[Note: The following is merely my theory of how I would apply my own personal standards of logic and judgement; I do not "punish" players at all on the Tribunal for personal reasons.]
Following My Standards, some examples of my "judgement" outcome would be:
Ex1: 5/35/10 <-- that's intentional feeding in my book.
Ex2: 5/25/6 <-- comes really close, but this could have been just an extremely terribad game for the player [check his profile *match history* at this point, and see if he has a long streak of "defeats", and use his scores].
Ex3: 0/15/1 <--- again really close, but not quite [in my opinion, anyway]. This also could have been a really bad game for the player [rinse/repeat above steps].
Ex4: 0/10/0 <-- unless this guy openly admitted that he was feeding in the chat log, it could have far too easily been a bad game, so give him the benefit of the doubt.
Ex5: 1/23/2 <--- Intentional Feeding! *Shao Khan's voice* PUNISH HIM!
Note: This is my logic and reasoning behind it. However, I personally do not actively engage in punishing anyone on the Tribunal for my own reasons.
