As the mods have pointed out, the reason for the seeming disparity in fair treatment is likely because PVP posters tend to fight their own forum battles when things get rough, whereas the other side tends to run and hide under the skirts of the local authority, often abusing the reporting system. The mods have suggested that we should take official responses rather than defending ourselves directly. I can confirm that the system works both ways.
Back in the good old days of negative rep - entire brigades of pew-pews would go into a feeding frenzy in an attempt to "send PVE players a lesson"
Oh how I miss them. Cute little things. Think they stormed off in a huff to some other game in the end.
