[Request] Account Locker

So everyone knows that when you enter wrong password too many time you wont be able to login for a while. Also there is a way to "login" without the client by sending a form to rotmg server.

So my idea is to make program that tries to login by sending that form like once in 30 sec with wrong password. Idea of this is to make your friend unable to login (only if you know his email obviously)

Any thoughts about this?

This data is stored client-sided and doesn't work because if you restart the client it will allow you to try again, plus you will just be making yourself be unable to login to the account not the victim.
