As I understand it, the disguiser role allows you to kill someone and 'erase' their identity, causing your own death to not appear at the beginning of the day phase, and make it look as if the disguiser had died-- and they assume your name, your color, and can chat as if they are you. If you or someone else is killed by a disguiser, what's preventing them from trolling underneath your name? Is there anything within the end-screen that implicitly reveals if someone was disguised or not, or who the disguiser had assumed the identity of?
I'm sorry if this question is completely obvious, but I'm afraid that it might happen to me in the future, and I'd really not like my good name sullied by some troll using that role for malicious intent outside of the game. It feels like it would be far too easy to grief during the game, then when it hits the endscreen, suggest everyone report the person you were pretending to be.
