Why the netcode issue exists, and why it cannot be fixed.

At any rate usually the most common 'hacks' are really exploits. That is, doing stuff that is legally acceptable in the game in an unintended way. It's very difficult to hack your client to say "I have no GCD", but perhaps you can find a tricky combination of abilities that somehow reset your GCD. It's hard to say "I have Godmode", but perhaps you can find a clever way to stack certain buffs/items to have 100% chance avoidance which is usually good enough. Exploits cannot be stopped architecture design, because what you're doing is allowed by the game.

How do hackers steal gil when an online player goes near a market board? I've never heard of anything so crazy even in the dime-a-dozen Korean F2P MMO's. There's some pretty serious issues/vulnerabilities with this game. There's days I think SE took the 10 years of accumulated knowledge and experience they have in this genre and flushed it down the toilet before they set out to make this game.

I don't know the details of that particular exploit but I thought they found a way to get other people to buy stuff from them without that guy even being there. It'd still fall under the 'exploit' category. A hack would be me taking over your account and grab all your money, and it's clearly not what's happening as the accounts themselves are not compromised. And it also highlights the real serious problems with MMORPG tend to be exploits, not hacks, so gutting your netcode to stop hacks isn't really that helpful.
