So., many years ago when I played Runescape (long long time ago) at some point there were many people abusing the game, or griefing people like I often encounter in Second Life as well. Both in random places, as well as new residents landing spots and the firestorm help sims.
At a certain point they introduced Player Mods, in order to assist the Jagex employees to act faster on this kind of behavior, those player mods had limited powers compared to the company employees, but could still do some direct action to solve issues with griefers.
I imagine that perhaps this would be interesting for SL as well, as I come past griefers almost daily at random places, and it seems to take a long time for LindenLabs to track/react to all abuse reports submitted by dozen of people, sometimes 40 times about the same griefer. A Player Moderator (PM) would be able to handle this faster, and with a PM abuse status / temp. ban it would be easier for LindenLabs to deal with this kind of behavior faster?
(not sure what category this goes too... so I picked avatars)
