What is the best way to report people for this. Other then the kind of unless in game system. Hard to report someone when they leave the lobby. Link is below if anyone wants to see it, They actually ended up in the mid game kill cam for DOM.
and if you can, see if you can't get some kills of the boosters! i ran across this other day for the first time. i got around 4 headshots from the boosters. then they stayed in the lobby and i reported them. i also followed around the booster on my time
the rest of the game just to **** him off.
Using the in game report feature does work. Sure you may not notice action taken against them immediately but with some issues, such as boosting, Treyarch has to investigate that player to see if they were indeed boosting.
