Valve already said that multple reports in the same game don't do anything.
So if 1 guy is being such an asshole that 9 people report him in 1 game, it still counts as 1??????
If that's true it's kind of stupid
I'm only reporting if they're annoying about it. I hate it when people go: "report xxx plz", I've never run out of reports since I started playing and in my experience the people who call for others to be reported are usually the ones who should be reported.
Most of the time you can easily recognize if the person asking for the report is the one that needs one or if he's correct about the request, so yeah..
