Okay, so always pondered about this question, because I was banned on a different server (not SGM, had the ban appealed shortly thereafter) for this. So I love to play TTT with my girlfriend, and we always personally call each other just to have conversations after we die or roast each other. But we swore not to ever talk about our roles in the game, so we can make the game fair. We are both very honest people, but I'm interested in your take, especially from an admin's perspective, is this still considered ghosting? It might sound like a dumb question, but I just want to put the question out there cause other people may not know either.
If you are just talking and playing on the servers and roasting each other after the fact, then thats completely fine. If you start telling each other information about the game that the other may not know thats when it becomes a problem.
