But seriously it makes no difference, for the real thing we will call everyone "untrusted-delegate-do-not-vote-XX".
Why should you do that?
The delegates participating in the test runs are the best you/we have (at the moment in the universe?).
Anyone is free to register new delegate.
The initial delegates could start with insignificant amount of votes so that they can be voted out if they arent "good" enough.
What is the reasoning in naming them untrusted-delegate?
