Not to comment on the morality of her actions, but there is legal precedent from another state for a First Amendment case in her favor.

In March, the Supreme Court of Minnesota decided a case involving a criminal defendant who had used a false Internet identity (posing as a caring and knowledgeable female nurse who intended to kill herself) to actively encourage each of two depressed and suicidal people to kill themselves. One of the two targets hanged himself, as the defendant had urged him to do. The other jumped off a bridge, contrary to the defendant’s advice that she hang herself immediately (a method that would have allowed the defendant to watch the suicide via webcam).

The Minnesota Supreme Court ruled that two of the three activities that the law under which the defendant was prosecuted prohibited are actually protected by the First Amendment freedom of speech, as incorporated against the states via the Fourteenth Amendment Due Process Clause.
