If I see anything in their text that goes to the extent of calling someone a name such as "person with downs", "retarded", or anything to suggest they have a mental issue, or talk about any type of sexual abuse etc, I will punish them without reading anything further. That talk is filth and as someone who has kids and friends who have suffered with that I will not tolerate it.
I've seen a case where 6 people reported someone for verbal abuse, and the only text they said the entire game was 'GG Noobs'. There was no option for "tell him to pull his pants up, brush his teeth, tell his mom he loves her", so I pardoned.
I wish there was a way for the tribunal to raise cases against others in the text of the match being reported. Such as "Hey, the guy being reported should be pardoned, but this other guy needs to be looked at".
The feeding one is hard. I look at the players level. If they're under level 20, and they are like 2:8, I don't consider that feeding, especially if they're running a support char - who should not be trying to get kills.
