If you neglect to take these steps, and fly a weak cargo ship blindly into an active CG system and fly straight to the target station with no regard for who is following you, and fail to submit or win the interdiction, then have no idea about what system you can hi-wake to and escape, yes, you can be ganked by a wing and have no chance at survival.
Some players don't have a lot of chose as to how powerful their ship is. Since I've seen a type 9 taken out in 3 seconds by 2 ships; I'm going to assume insta-kill is a real danger for these players that they cannot high-wake out of.
And I'm not talking about people who let themselves get in over their heads... who have wandered into a HazRez, or picked a fight... I'm just talking about people flying around.. maybe hunting at a nav point, or trading, who are attacked by players.
In a crowded system, it's not possible to keep everyone away from an angle where they can interdict... and when you are mining, or at a nav point, or a station: it's not even requiring an interdiction. Can we agree on that much?
My issue here is twofold.
1) I don't think the real complaint is combat logging. That's just a common mechanism. There's this outcry (it's hard not to call it "whine") to ban combat logging as this "root of all evil" from some "it's cheating" bully pulpit; but it doesn't seem to be the actual problem.
2) The game, lacking a good crime-and-punishment system, lacking actual safe spaces (in open) for noobs, with a system where insta-kill is easily achievable by an advanced player; fails to give many players a way to not get "random ganked".
Let's imagine we manage to "punish combat loggers". I predict 3 things.
1) You'll punish innocent people.
2) People who are not in the group that's actually bugging you will get punished for clogging to get away from gankers, griefers, and accidental police aggro.
3) The actual people you are complaining about will find some other tactic and the complaints will continue unabated.
So you'll spend a bunch of money, create two new problems, and not really fix the one problem you have now.
You know.. unless the goal (as seems the case for some posters) is simply to make some people's lives more miserable on principal.
