Since the need of members to get auth granted as if there was no tomorrow. The moderators are doing a great job reviewing every topic, chasing for +rep beggers etc.
However, i've seen somewhere out of this forum that people arrange to make several accounts and upvote each other (each day max 2 reps i think, but multiaccounts would make it get faster 11 rep...)
Anyways what i suggest is to make a separated "Trusted reputation" that only Contributors/Trusted/Royals and onwards are allowed to give (Max 2 rep/day if necessary).
This way new users would need this kind of reputation to get auth access, and we the members who have helped more to the community, become the persons who choose who deserves this rep.
Just a suggestion, and also able to be improved by anybody.
EDIT: I accept this can be a bad idea, so no problems in criticism.
You shouldn't agree with me just for my rank, feel free to comment.
EDIT2: Improved rule would be to have >10 normal rep and >2 trusted rep.
