If Valve added a feature that enables players to dispute/argue over wrong accuse/reports, players like Quinn would have a standing whenever they are reported over a game they did not even trash talked/Griefed/ruined the game in any way possible.
If they employed players to review these disputes, I would gladly take the job and would even go for as low as 5$/hour doing so.
and who are you to say something should be regarded or not? do you work for valve or something? what kind of authority do you have?
