A simple question to those who demand Helga should be banned...how? What do we ban? Her username? She posts without one. Her IP address? It changes the next time her internet connection drops, almost certainly.

You are right, of course, that as a technical matter, an anonymous open system like wiki is always vulnerable to attack from someone sufficiently determined. The question is: is it possible to raise the threshold cost for the attacker sufficiently high to deter them, without also raising the threshold cost by enough to deter other, legitimate contributors.
