Temp Ban for False Pins?

Re-read his post and think logically for a second.

Anti-hack measures are supposed to penalize the hacker, and not the legitimate owner, whenever possible. With temp bans on accounts instead of IPs, someone could exploit the system to lock out a victim target account. With temp IP bans, only the hacker would get locked out.

Think of Nexon's reasoning: Who else but someone who isnt the owner of the account would get the pin wrong 5 times in a row?

But yes, I can see how constantly blocking someone from their account could be exploitable
