The fact that Tox is not Hama is information that Neyra learned due to her role...

Hmm, no, that's too much. If she denies her own role, it will only have a negative impact on her. Something similar happened in Koshi's mafia game, and it happened somewhere else too. You can't state it directly, but giving strong hints, especially when your role is already understood, or in a situation where two people have the same role, is perfectly acceptable. You shouldn't blatantly hint when your role hasn't been revealed yet, but if it has, denying it is bad for your neck.
