Despite them wanting PvP, I've learned that PvP to drive them off does indeed work. Back in 4.84 Sigma-13 was a real mess, many, many lolwuts in caps literaly chasing OORP Diamond/Niobium traders. In all that were some serious RP'ers. On a routine basis in GMG|'s early days, we routinely went out in a group and systematically brought down anything OORP that our ID's allowed us too. For 4 hours the system gets freed up with only individual trouble makers trickling in to meet a system full of veteran RP'rs. We didn't even go for known good RP'rs that are targets for our ID until we removed the lolwutter's and than began serious RP'ng with what was left, doing the cat and mouse thing but essentially stalled and let the better RPing pirates have a go or two at OORP traders before chasing him down. PvP, used judiciously, works at warding off PvP whores.
