Anonymous Imposters

Hello!

I’ve been using this great plugin but I have a critical question.
My site is built for anonymous users and this creates a serious problem.

Let’s imagine a scenario that a user posts his first comments with a nickname.
Then second person comes and comments, pretending to be the first one, since he can fill in the same nickname, so no one knows who is who and everybody can be an imposter that way.
This can create a pretty big confusion and frustration.

Is there any way to resolve this for non-registered users?
If not, the simplest solution would be to remove the whole username field so nobody can have a name, thus be cleaner in a way.

Please let me know.
Thanks!
