I have seen a few members with "Anonymous" and "N/A" as the people giving them rep. What is up with that?
Obviously the person who gave the rep chose to give it anonymously...
This idea is designed to rep people (usually badly) without knowing who did it. For instance if I wanted to -rep someone for doing something offensive and I didn't want him or anyone else to message me with hate then I would anonymous rep.
Case solved.
Oh, I never knew you could anonymous rep. Also, what is N/A then?
N/A usually means Not Available.
It's to prevent rep freakin
N/A is what is shown when the rep was given by an account that no longer exists (ie. has been merged or deleted).
Anonymous repping is a feature that you can use when giving someone rep so that your name isn't shown on their reps.
