There was talk of resetting them a couple of years ago, but they never were. The numbers you are looking at are the original numbers for each player. Guests are allowed to howl and growl too- anyone with an account on the forums can, so it could really be anyone.
For those who used to be around in the original days of RAtC, they used to be called "Props" and "Smite." The overall feature is called Karma, and it is a feature of Simple Machines, the software we use for our forums.
Do people think it's time for the numbers to be reset? If people are not happy with the feature, it can be disabled.
