The game - the devs - don't take responsibility about any sort of PK'ing, ganking, griefing, pirating but also not for any usage of other legit game mechanics like blocking, menu logging or simply playing in Solo/PG. The game/FDev is totally indifferent against these things and any claim from players this or that isn't right is just stupid peeing against the wind.
As much as I support everything that Sir Ganksalot does, and I do not encourage menu logging, it is as Frillop says here a "legal" tactic, meaning that menu logging will not result in ban. (Task killing absolutely will, and it's quite easy to tell the two apart - they present differently to the attacker).
It's another one of those mechanics, like toothless C&P and the meaninglessness of "high security" and the like, that results in some unfortunate responses and behaviors within the playerbase. We've gone over them already so i won't repeat the discussion here.
To me, personally, it doesn't make any sense to play in Open but then menu log when getting interdicted. It also doesn't make sense to me to play in Open and put people on your block list even if you've never encountered them in-game, just because you know they are a ganker.
However, both of these things are fully within the rules, the ones I have agreed to that in the same way that I fully expect a player in Open agrees to being engaged by me. Since that is also fully within the rules.
Where there's so much acrimony is, to me, when people either don't understand the rules, or refuse to accept them in the terms expressed by the "rulebook", aka the game and FDev.
Please note, agreeing on what the rules are, is completely different than saying someone is being a jerk or similar. Unfortunately, that discussion inevitably gets mixed in with the rules discussion, leading to more dispute.
