Well as far as "advices" go, I would say that if you really want to be a "mad hacker", you should probably do a tool by yourself
If you want to recover your own pasword...then you can always have a program that "enters a digit , presses enter, enters a digit+1, presses enter" and so on
And if it's not your password...just remember that even if they don't block after X tries, they can still record the IP where the billions of tries come from...and depending on the gravity of it, that's a felony
