In theory, there could be an intelligent psychological model that analyzes a male VC's brain and provides thoughtful suggestions to them to dissuade them from this behavior right before it occurs. While that's a nice thought, it's incredibly unrealistic.

The far more practical approach is to catch the bad guys over and over again, make examples of them and mete out punishment. That's how criminal deterrence works in every other field. No reason to make an exception here.
