The flip side of that is that will scare women who genuinely were (already too few of which pursue court cases) from instigating proceedings.
The annonymity is fine (I think) but the malicious prosecution charge will be a step too far I suspect.
The issue with rape being treated differently is two fold: Firstly rape has made it into a much more socially unacceptable thing to do than other pretty horrific crimes, including Murder, and seem remarkably disinclined to listen to a jury returning an innocent verdict.
Secondly, because the base activity can be perfectly legal in many circumstances (the difference is one of permission) the case is far less clear cut in any of the difficult instances.
