I don't know if anyone does it large scale. It's the counter argument to 
"just do it at the domain on the account". Obviously we see attacks that 
are probably of the form admin/admin, admin/password, etc on standard 
accounts guessing standard passwords either against SSH or AD. We've 
also seen individual user accounts be hit, and using AD lockout, it ends 
up being a DoS against those accounts. Don't know what the end goal was, 
DoS or online brute force an account. In either case, I would rather 
stop the offender than punish the victim. There is documented evidence 
of attackers triggering the lockout on administrator accounts, trying to 
slow down a response once they've gone overt.

And yes, phishing is way too simple. Up until recently I think they were 
having a competition on how bad they could make it an still get 
credentials. I'm not sure what my Pessward is, but they certainly were 
trying to get it.
