An excellent post, describing circumstances where players are demonstrating an ability to hold ground (ie force other players out of a system), and accepting the consequences of losing gracefully.
I think all three examples can be simplified as Bounty Hunter vs Pirate, where the attacker is chasing off a 'baddie' although either side may or may not be wanted.
I feel this comes much closer to voluntary PvP, and here the punishment for CLing (on either side) should be harsh.
This makes me want to reconsider Ganker vs sheep, because I can see how it would be difficult to recognise the difference between a legitimate attempt to apply overwhelming firepower (Ganking) and an undesirable one done for lols under a thin veil of plausibility (Griefing).
Truesilver, can you come up with a workable definition to distinguish your groups actions from those of a griefer?
Thank you for the invitation but I fear it's beyond my wit, at least in the current iteration of the game.
If we take three examples:
(1) Ronin of Amarak not letting anyone who isn't RoA into Amarak
(2) Adle's Armada attacking a 'Clean' Cmdr in Eravate because he is known by name to be a multiple murderer
(3) Imperial Cmdrs going to Rhea to attack Winters Cmdrs
Only the third one is capable of evaluation by the game (by reason of both sides being pledged).
Concerning the other two, although I personally consider both to be valid, many readers of this forum would presumably want to prevent (1) while permitting (2).
(Hence, presumably, not punish someone who logs in situation 1, but punish someone who logs in situation 2.)
While I personally strongly disagree with value judgments about combat logging, even if we were on the same page about that, I don't see how a game can effectively judge a player's situation or prior actions in order to decide whether what we have is a morally 'good' or 'bad' log...
And I must repeat that I am with Rinzler on the fact that considering some rules of the game to be unfair is not a valid reason to break others!
