Despite it being abused, It did help clear out botters, just nexon designed it so poorly. What they could of done is make it so the person getting targeted once by detector is immune to any others for about 5-10 minutes. This would both solve the legit players abuse and botting.Oh... you mean the lie detector item that was eventually removed because the majority of people abused it to grief and steal maps.
The community can't be trusted to police itself when provided the tools, so the ball was taken home because of it. If you play Combat Arms, it's no different from Elite Mod players kicking you from the room because you killed them too much.
