The answer isn't moderators in hi spec ships. It's giving purpose to PvP.
I'd love to make creds helping to defend traders shipping high value goods. But I can't. I have to wait 'til a pirate kills a trader so I can cash in on the bounty.
I think the majority of 'griefers' (I recognise this term means many different things to different people on these boards) would disappear if people had something to fight for: territory, control of trade routes, protection through hostile space and player politics more generally. I'm sure Wings will help to some degree with grouping mechanics; but those groups still need to have a purpose beyond sharing creds from bounties.
