Does she though? She had every reason to believe her choice of email address would remain private.

By a similar token, I am currently working for <REDACTED> (on lunch break) and using a computer belonging to said entity. If you managed to work out what <REDACTED> is, would I retroactively be considered to be speaking for it?

If you are a mere student who was later uncovered to be an unsavory Twitter person, do you speak for the institution? In some ways you do, and in some ways you don't — whether or not you or the institution likes it that way. Similarly, if you are a judge or lawyer and you're later found making unsavory statements about ethnic defendants, do you speak for the institution of law? That is up to the public to decide.

Credibility and reputation aren't precisely in anyone's hands.
