Login twice on same account? Good or potential security risk?

I think they should allow multiple login on the same account, with the following safeguards:

- If it's the same IP as the already logged-in char, allow login automatically.
- If it's not the same IP, pop up a verification request on the first logged-in char's screen.
- If the verification request is denied or times out, allow the new login attempt to override by inputting birthday. This method will kick off the first logged-in char. (This is to be used to kick off a hacker that might have gotten on your account and is now blocking you from getting on it yourself, or a disconnected-but-Nexon-failed-to-detect-it instance).

This would be very nice, but I think Nexon would be waaay too lazy to implement all this.

In fact, this issue is likely due to lazy programming/troubleshooting. Instead of tracking down why logged-in status occasionally doesn't get cleared after someone d/c's, they just now ignore logged-in status. It's just luck for them (or more careful work by former programmers) that this does not allow item/meso/nx duping.
