Is it still considered ghosting if a dead player tell the living that ''Player is a T'' but when Player is killed, it is found out Player is actually an innocent?
Telling live players ANYTHING that relates to the game is ghosting, even if you're lieing, the living player may become more prone to RDM the innocent due to your information.
So I have been situation where thier is two left and they are playing hide and seek would it be ghosting if I tell the t to buy a radar??
Yes, because you're saying something to alter the outcome of the game. The only exception is, when I asked @Highwon about it, if the last few players are delaying and it's been awhile, staff only may message the traitor to buy a radar.
