or just pretend they just missed to press the button when his/her friend went by and then kills all the other players so its just them to alive.
This is not an example of ghosting, this could be somebody letting people pass the trap so others think its safe to go, then he uses the trap to kill multiple people.
You don't mention that the people who ghost are dead players, alive players who are running the map and give out information are not ghosting they are just helping there team.
if they continued disrespecting. If it was just someone trying to disrespect someone i would give them a warning (maybe gag/mute them)
If somebody is disrespecting a player then you will want to gag/warn them before muting them, this is because it stops them breaking the rules. Then you will warn them for whatever they did.
I agree with stratiic when he says you need to me more professional in game, sometimes you can be immature and use your microphone a lot of the time.
For now
If you make these changes I will change my verdict
