Never going to happen. First, no developer is going to appoint themselves a judge in what's griefing and what isn't.
Second, there is kinda no point in enabling players to shoot at each other, then punishing those who do, eh? It would be like giving a bunch of kids water guns, then yelling at them for getting wet.
Third, those players who like to PvP, which involves shooting other players, paid money for the game just as anyone else. Unless they put in "firing weapons at other players will result in your account being flagged as antisocial and put into a segregated instance forever" - which they won't - they will have no right to segregate anyone on the basis of how friendly with their guns they are ingame.
What those who can't stand the idea of another player shooting at them CAN do, is segregate *themselves* from those players. They can't however, force those players into being segregated from everyone else.
Which is why this thread is silly. In Eve, there is no getting away. Here, you just switch to private/solo or add them to your ignore list, and then you don't have to worry about anyone.
I wasn't suggesting to flag it for one or a few actions you take. It should involve loads of prerequisit's. On how many igoner list you are how often over a course of a week attack's occure without reason (no pirating action or special area something like attacking in no fire zones). And it wouldn't be a ban but set to another group so they wouldn't be matched with other non flagged player's. And also not an automated assignment of this account state. You should also be made aware of that this state is set to your account with repeal option after a grace period.
But the ignore list should suffice yea.
Would drain quite some resources to moderate this group and it is quite questionable if it is even necessary to do so. Would need testing.
But this would be an option to handle such massive groups that are only out for 'dominating' the other player base. They could still play but then go hassle others doing the same.
And as i stated this wouldn't solve them affecting the overall universe market and event outcomes.
And never say never. I remember that some game either proposed or implemented a similar system i just can't find it again. Well maybe i just dreamed it or i got it from a proposal on the forums here.
My point with the comment was about how does something like the OP brought up even affect the enjoyment of the game the average player.
I see 2 point's getting in the crossfire of farming ganking, not being able to meaningful affect the big event's and market crashes.
The main concern is the ganking part which hopefully will be solved with the ignore list. But if it fails this extra group system could supplement it.
In my expectations we want market crashes and falling system's, as i stated. Will Bring up interesting new event's, missions and trade opportunities.
The only problem are the big event's we could affect. Making them moot if there are giant organisation of players making the outcome certain.
