I think her decision to take this to twitter was the completely wrong decision. She is a developer evangelist at one of the most important developer conferences. She is representing SendGrid on all of her public forums.
How does the public alienation of these two guys go towards building critical mass of support for SendGrid? Even if this was sexual harassment what would she have gained for herself or SendGrid by bringing this to a public forum. She has to know that a large number of potential SendGrid users are men who have similar senses of humor.
If she was deeply offended by the comments these guys made she should have spoken to them directly or privately mentioned it to the staff.
