I thought of this idea in the shower xD
Anyway, I'm not sure what anyone would think of this idea, but I think it'll raise security on your account. So here it is.
If you fail to login 3 or more times before imputing the correct password you will be asked to answer a security question. The security question would function like other secuirty questions, you must answer the question to get onto the account. (The user can set the password in preferences or choose not to have one at all. )
With this in place, it'd lower the chances of "guess hacking."
It's just an idea, say what you think^_^
EDIT: I know a moderator will come along and say"They could just choose a safer password," but to that I say"Just ask Maveroni what his password was when he was guess hacked."
