You bet they will. It happens all the time. I have been involved in cases where females have claimed that they were sexually abused ect and after extensive investigations and lots of man hours and money spend it comes out that these women were lying. And the reasons why they lied tend to come out in the wash as they say.
Your assertion is based upon the assumption that these were actually women and that they actually had interactions with Wintrich and also that these alleged women were telling the truth. Potiphers wife did what she did as a women scorned and yet she had no compunction about playing the attempted rape card. I don't think saying that one has been sexually assaulted is anything but opening up to humiliation. In Potiphers wife's case her self imposed feigned humiliation served an agenda and was the result of her bruised female ego.
Given that these women did not leave their full legal name on CB and I am wiling to bet that they did not leave their full legal name and perhaps even their real name in their tweets, there is little risk of these alleged women opening themselves up to humiliation.
