New hacking epidemic

Assuming nexon ever actually implemented anything suggested on random forums - Maybe.
But that'd also be an easily exploitable duping mechanism.

I would think of ways it could be implemented without too much hassle:

By clicking the button, the servers:

Code:

Check if the account is online.
If the account is online:
  Find the character online
  "Emulate" that the character presses the log-out button.

In that way, the servers would not do anything they haven't done before, correct? The only way to abuse this would be if something out of the ordinary happens if you somehow manage to drop an item and log out at the same time, but I would suppose there are synchronized threads working with the characters at Nexon's office, and not asynchronized ones.

Then again, it's not really worth it. Nexon should rather fix the exploits instead of having an emergency-button somewhere for the users.
