I think I will have to respectfully disagree with you on that point. The griefers will say this but they are usually the same people who pk allies and will not leave a safezone without a ppu. There will always be cowards in everything and people who absolutely have to bring entire teams of people to "grief". Uranus was full of them. We had "gank" teams who used to regularly bring one or two ppus to fight in their gank teams. They told us they did it because they could.
We just went and took all of their ops instead and made them fight us in a battleground sector and beat them 2 3 and 4 times over until they got tired of coming back to die again.
No theyre not one and the same. I am a pvper and I do not gank anyone unless they shoot first.
