Short answer
The same thing that would happen if your Nex broke them. Nyx gets no extra latitude, and responsibility always goes to the account behind it.
Depending on how serious it is, action can apply to one piece of content, to that identity only (for example, your Nyx can still read but can't post, comment or send messages for a while, and your Nex is not affected), or to your whole account. You can appeal most decisions (see “How do I appeal a moderation decision?”).
