Let me tell you from first hand experience, (been playing on and off since 2004).
Yes, there are those who would gank newbies just for fun.
They are far from "very advanced veterans that would spend tons of time playing". The "very advanced veterans" have much better things to do in the end-game, than gank newbies at a loss.
Those that are ganking newbies are not very advanced in terms of game progression, you could do that within a week even, if not less. It's just that it doesn't take much to kill a newbie ship.
Absolute newbies (those who just started) are safe from griefing. The starter systems are highest security, and pilots that shoot unauthorized targets gain negative security status, which prevents them from entering those systems.
Even more, the game developers made it a bannable offense to grief newbies in those starter systems.
Will they still die? Yes, and they will get a free replacement ship, while the killer will have his ship blown up by police (which is much more costlier) and won't be able to return there to continue griefing. Would a new players quit over this? Prolly, but then we didn't want that weakling anyways. For others, they would have learned the lesson, gotten smarter about the game and continued.
The only way older players would be able to legally [in-game] shoot at newbies (which is a bannable offense out-of-game anyways) in the starter systems is if the newbie committed a criminal act.
This is again a great lesson, as you would rather learn the criminality-system in a free starter ship, than in something expensive. The most common "trick" older people would use is to trick a newbie into stealing jettisoned cargo outside the station. Well, guess what, even ED punishes you for stolen cargo.
At least EvE made new UI improvements that prevent newbies from doing criminal acts, without first warning them that it's criminal. This was a rather new change, and quite needed, as before they game didn't inform you that your actions were criminal.
But just like in ED, it's common sense. Don't steal in front of authorities.
A lot of elitism and exclusivity here. Which is the same behavior on a different part of the spectrum that we see from PvE players calling normal PvP interaction "griefing".
I do not endorse this product, and this is a good example of what I meant by saying I had found that all of the dead wood that is currently being trimmed from Eve seems to be finding it's way here.
Amazing how the extremists always find themselves to be the representatives of a social group, when outside of that group.
I used to have a lot of fun exploiting this mentality for profit in Eve, and I'm going to have a lot of fun doing it in Elite. Every time I visit the forums my excitement grows because I see more and more gameplay content laid out before me in the communities behavior.
