So, it doesn't look like Malka had a physical/sexual relationship with the victim prior to the accusation, just friendship, based on her accusation and his response. Further, she herself admits they later did hook up. She also didn't name him explicitly in her brief sharing of the event. Malka's rebuttal, if that's true, going on about infatuation and accusing her of being psychotic, that's the kind of shit sexists and abusers often do. The person who accused me is psychotic! What a wet dream for some men. There's women out there who want me or want me to hurt so badly that they'll risk their entire reputation to slander me! Men who believe that have too much ego. Malka has a history, according to accounts, of being a bit too "hands on" with women, so that makes the accusation somewhat consistent.
As for trying stuff like this before courts, there's little to try. It comes down to he-said she-said. Courts demand a level of evidence that is simply impossible to provide in situations like this. Unless you wear your Google Glass everywhere, how is it possible to prove or disprove this event? Nevertheless, people have a right to form opinions of folks, and as a non-involved party reading information after the fact, I'm more inclined to believe the victim in this case. A number of studies estimate that false accusations are far less common than legit ones. Most women have very little to gain and an awful lot to lose when making accusations. The penalties to women (and men), both physical and social, for making accusations are severe enough that there is every reason not to go public with accusations. When people do, it is usually to try to put some personal demon to rest or help comfort others who may be experiencing something similar. I'm certainly not saying false accusations don't happen, but there is this very strong tendency to question and blame victims. What do most people have to gain from false accusations? Nothing that would justify the personal cost, in most cases.
Before folks try and turn this too much into a political football (oops, already happening everywhere), let's remember that hypocrisy happens regularly on both sides of the aisle. Left and right political ideologies (and even religions) are littered with people in power who abused it for personal gain.
