Addressing Serious Hacking Issues

They should be going after the hack programs themselves, not just 'improving security.'

Do you try to stop rain from being a possible weather pattern or do you water-proof your house?

When you're under siege do you try to kill the army that has you surrounded and outnumbered, or do you fortify your walls further and try to wait them out and keep them from finding ways in?

Not in a useful way. Even if the packet is signed right, if the server refuses to swap the player's item/meso for the requested item, there's nothing they can do about it. That's the kind of check I'm talking about.

Essentially the same problem & answer CrazyNomad quoted me on from over a year ago.
