Partially: UA (I will finish the code) can be used to identify spammers by analyzing their followers. But in a Utopian context, we already have manual reviewers: the moderators, and only manually approved contributions receive an upvote. On top of that UA can be implemented as a metric inside the Utopian bot code as well, analyzing the UA of all manual upvoters as a metric for the weight of the Utopian upvote to post X itself.

And the "elite member" I understood of course, but then the problem becomes "who gets to determine if authorX is or is not an Elite Author"?
