He was not harassing her, she just had an unpleasant conversation with him (from the sounds of it). If that is reason enough to out somebody on the internet as a sexual predator, I'm sorry, but that's way over the top.
While the guy's behaviour was blatantly inappropriate for a professional meeting I'd hesitate to say he was harassing her in the active sense. That has different connotations to me anyway.
Still, if he can't resist unprofessional misconduct whenever he meets a woman this sort of public humiliation might have been sadly necessary.
Titles wrong, which is a good reason to have left it as is. This is libellous.
He was not 'harassing' her. It was one incident. All other communications was by her.
Also not clear if he was representing his employer at the time. So it also shouldn't have been stated. It's not a witch hunt.
