When I played Asheron's Call, there was a server called Darktide. It was an unrestricted server with Free For All PvP as its main drawcard. As to be expected, this meant that anyone playing on Darktide was a target of the Player Killer (PK) especially those players new to the server. Lot's of these players got together and formed guilds on that server wholly devoted to ganking anyone that crossed paths with them.
The there were the players who liked PvP but were opposed to the wholesale slaughter wrought by the PKer. Like the PKers, these got together and formed the Anti-PK guilds that didn't go seeking out the weak and alone to gank, but set out to help them by protecting them from the PKers, and actively fighting against the PK guilds.
Asheron's Call wasn't alone in this. Ultima Online also had players who banded together to oppose PK players.
I have a question for you. I hear a lot about the corporations and alliances in Eve Online that engage in PK activities where it's encouraged to go out and gank all and sundry. Each year (or few months) the Hulkageddon event takes place where players vie for prizes for high-sec ganking of unarmed/undefended commercial spacecraft like the Hulk. The Goonswarm alliance is about to set Jita on fire, which means that lots of highsec non-PvPer players are going to get burned.
There seems to be lots of FFA PvP in Eve focussed on ganking.
But I hear very little about the player corporations that are set up to oppose that sort of behaviour.
Can you tell me. Are there Anti-PK corps in Eve Online?
