Why the Secret Spell Scroll system would have never worked.

Frankly, I'm kinda just waiting for the day I inevitably get hacked.
Then I can stop even checking in on this game.

Such an exploit was predicted months ago and, if Nexon were concerned at all about the integrity of their game, they should have had an employee discover this hole and implemented a preventative fix.

All the hackings/exploits this game faces wouldn't bother me nearly as much if they weren't so obviously predictable.

I see so many people saying this.
How about we look at how nexon handled similar situations?

You mean roll back to a date that only affects those who used the exploit after it had become public, thereby leaving all the prime benefactors untouched?
