Pretty much the title sums it up.

Valve does not punish people who grief games, afk, intentionally feed if you report them. They do absolutely nothing in this field themselves, unlike other games like league of legends which actually individually investigates reports against other players.

The reason valve does not investigate into each report is because they are 1. Too stupid to implement that into this game themselves. 2. Too lazy to put into the work to learn how to do that from other similar games and 3. Too greedy to expend resources on making a quality game.

Not only do they not punish intentional griefers, they also automatically punish anyone who dares to leave games that are being ruined by other players. Becuase they apparently cant be fucked to implement a concede feature into this game.
