If someone asks a prop that is being possessed on who the T is (mentions their name, if its a T, prop jumps, if not, prop does nothing), is that ghosting? I mean, it's RDM to kill based on that, but is it ghosting?
I would definitely call that ghosting. A dead player is using means of communications outside of global living chat to notify players of who the traitors are.
"Ghosting Using third party chat to inform player of in-game events they are not yet aware of. Using public chat, team chat and spectator chat will ensure you aren't ghosting. Any other forms of communication could result in inadvertently ghosting and we will enforce it." Using this servers definition of ghosting, props saying yes or no to a question from an alive player is indeed ghosting.
They are not exactly communicating through third parties though. Its not enough to kill for so much as place suspision - as I have seen groups mob innos before but I WOULD consider it prop harassment. As a spectator you should not influence game play as a prop. Remember people, it's a privilege not a right.
I had one situation where almost every single spectator possesed a prop and surrounded and pushed the last AFK T. And players got highly suspicious of the T.
The key part is " Any other forms of communication could result in inadvertently ghosting and we will enforce it." A spectator communicating through props is not team chat, public chat, or spectator chat.
If the prop is responding in a consistent way to questions in a way that purposefully reveals meta game information, how is it not communication. It's like nodding your head yes or no.
The answer is yes, it is definitely ghosting. I have watched players try to have a bowling ball lead them to the traitors on Bowling Alley. The thing that makes this ghosting is that they are using means of communication outside the realm of living team and global chat to give players information that they're not yet aware of and could potentially change the outcome of the game.
