Do trolls deserve anonymity? What should we do about it?

Based on the never decreasing problem of trolls abusing the privilege of anonymity, the internet must do something to end it. Throughout this unit I have heard two different views; both of which I cannot fully agree with. Therefore, I propose a third option. This option includes a little bit of both. The first view includes taking away anonymity completely while the second says keep it because the ones who don't abuse the privilege shouldn't suffer due to trolls immaturity.  Well I say we ban the sites that don't require anonymity and be more strict on what goes up on sites that allow anonymity.
