How about not going "internet police" on anything that hasnt moved the last 5 seconds ? If you qml people who really are afk they wont press m and you dont loose your multi. Also people who are obviously afk are getting pollkicked instantly by press 1 hungry ragekickers anyway.
Personally, I have only ever QML'd people who have not moved from spawn multiple rounds, as I see by spectating them. Cav does a good job of killing them off so you can't tell but not always.
Every time I have ever used QML, the person (who hasn't moved for 30 sec into the round mind you) presses M and then.. nothing. They continue to leech.
Also, pollkick doesn't usually work for leechers, unless they're the last one alive at the end of the round, people just shout "IT'S A NEW PLAYER, U F*KIN AMERICAN, U CANT KICK A NEW PLAYER!" when it's obviously not a new player. Really, I am surprised so many people make that argument....
