Nope. If you damage someone's reputation, and they can prove you were lying, then I see no problem with you being required to pay them back every cent they lost because of your lies. False accusations of rape are already a punishable offence. What needs to happen is for those laws to be actually enforced and sentencing to be balanced to the point where those found guilty receive the same sentences they attempted to impose on someone else. If it's possible for these conditions to affect innocent people, then that means that the rules of evidence we have for criminal cases are far far too lax and need to be tightened up. And I have no doubt they will be because people don't care until it happens to a woman.
