I don't know how they plan on making comments not anonymous. In this article the only defense is having users register. Which I'm assuming means that they would register with a valid email address and click a confirmation link. In that case services such as ShadyEmail.com and the like can get around this type of registration.<p>The only real way to stop anonymous comments and commenting is to make being a non-anonymous member of the community more rewarding and productive than being an anonymous member. It's not really a technology or policy issue, its an issue of personal incentive and community.
