I'm more lenient about small instances of raging or reports of intentional feeding that aren't obvious, so I pardon quite a bit, and it kills my streak a lot. I also have zero tolerance for flagrant swearing, AFK/Leavers, and harassment, so I'm more apt to hit punish where a lot pardon. I also tend to punish people saying they're reporting other players because they're having a bad game, or missed a skillshot that cost a team fight, or something similar. I tend not to punish if someone says screw this, I'm going afk or spams surrender, and a player lets the other player know that if they choose to do so, they'll be reported. I've been seeing a lot of "reported because they reported me" lately, so I've drawn a harder line on that recently.
