Was karenkhor IP locked as well? While she may have been account locked, what is stopping her from making another account?
I just want to bring this forward because I don't believe that there was an answer on this and it was skipped over?
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.
