Single post in Account Breach incident

I can answer that right quick. While I don't know the code behind it, ( halp, Niet ) if anyone tries to make an account on an IP with a locked account on it that will be blocked from creating another account onto that IP. Say there's an account ( PokemonFan1357 for example ) on your IP. Maybe it was your brother. You think "okay, I'm gonna make an account too!", but as you are creating your account a box pops upthat says - in condensed terms - "oh no! We cannot complete your registration process because there is a locked account on this IP!" Turns out, PokemonFan1357 was locked because they broke a rule too many times. Darn.
