Does this kind of public shaming on social media really help?

There was a thread on Facebook, a woman posting that her husband often drank too much and acted like jerk. This was a very public posting, it was in my feed because someone I knew commented on it. This is a woman in her late 40s, and at some point her husband commented, pretty distressed.
I scrolled past after reading some of it, but I am curious if this kind of thing ever has a positive outcome.
