Password Saboteur
I used to play a lot of backgammon in Yahoo Games – and some people were real jerks when losing. Most commonly they’d stall the game by taking the maximum 5 minutes per move, hoping I’d resign. I learned a way to boot these people off Yahoo for as long as I wanted, by trying to log into their account.
When I used the wrong password ten times, the account was locked for 24 hours. They couldn’t log in again until I chose to allow it.
