It is obvious that FDev does not want to implement long term consequences of behaviour. I suspect it is because in a video game it is too easy for a player to dig a hole too deep to be able to ever climb out of.
There is always "clear save".
So instead we have a blocking feature.
Frontier's propensity to conflate the game, metagame, and setting has long bothered me. I realize that some players have difficulty separating themselves from their characters and fantasy from reality, but FDev has no excuse.
I think it really dawned on me that the game had reached an inflection point when Sandro started talking about his ideas for a karma system that took into account things like disconnections (my opinion was, and is, that no number of accidental disconnections should be punished in any way--though the onus is still on the player to provide a stable client in a P2P game--and intentional disconnections to preserve assets, as cheating, should just result in an outright ban, treating them as the same thing, or letting the in-setting stuff acknowledge it in any way, is pure folly). Fortunately that never came to pass, but plenty of other lazy, 4th wall breaking, nonsense was allowed to fester.
Harassed as in interdicting them and disrupting their flow of ganking unarmed / non-pvp equipped ships?
Yes, that would be their perspective, which is as valid as any other, and an equally flimsy justification for them being given control over instancing.
Indeed, but if everyone would block gankers, the instancing would be much nicer and less disrupted, because only the gankers would be affected and nobody else
This is predicated on everyone having the same definition of ganker; no one wanting to interact with gankers; gankers being readily and unambiguously identifiable; and being able to communicate such instructions to all players. Pretty much none of those are likely to occur in practice, let alone all of them simultaneously.
Ask ten people to define ganker and you'll get fifteen different answers. Even when a rough consensus can be reached, gankers are content for many people, not only anti-gankers. There is also an enormous spectrum of activity that could easily be taken out of context and mistaken for ganking, no matter the definition, and land someone on some poorly corroborated list. Most players, especially new players, often have few contacts in-game and do not frequent the forums or Reddit, and may be ignorant to the point they don't even realize when they are being attacked by another player character, let alone that they can block future instancing, should they desire to.
