Now obviously the original lady was a rude, but so what? Somehow being rude to someone is grounds for public evisceration these days? Of course being publicly humiliated is way worse than being rude to someone.
This isn't the case of one person being an a-hole to another in public in front of witnesses who could repeat the affair and shame the offending party: it's a case where the offended person chose to make it personal and punish the other.
How exactly did the offended person punish her? By revealing to the world the true nature of KB?
And I don't expect my private message to become public, do you? Of course, messaging an unknown like that, you have to be more careful.
Maybe she just had a bad day, the message came at a bad time.
