This is a very good way to make some extra money but I would highly suggest you install
http://www.stopthathacker.com first.
Then you can set it to kill the leaked password after so many uses since you can't be awake 24/7 to know when to kill it.
If you are sleeping when they hit you and you don't have something like Stop That Hacker installed you could lose money from excessive bandwidth charges very very fast.
