Shared passwords may work for getting new members sometimes but hacked passwords are very different and will make you lose money.
Hacked passwords are passwords that are stolen from your site via a brute Force attack.
A Brute Force attack is when someone hits your site with thousands of usernames and passwords in the hopes of getting "lucky". Often they use a list of common passwords or whole password files stolen from someones pay site. Remember most people use the same username and password over and over again, so getting "lucky" is not that hard.
If someone steals a password from your site they are stealing a password from a valid paying customer, a customer that rebills every month. When you have to delete that password your blocking your paying customers access.
Think about it..........we all work so very hard to keep our rebilling customers happy why would you risk pissing that customer off by deleting his password?
The people who share passwords are not going to be rebilling anyways but the guy that is stealing valid, happy, paying customers passwords is costing you money.
You may not even know how much money your losing.
I have not even touched on the issue of increase server loads from the bonehead hackers that hit you hard and fast with a Brute Force Attacks.
Solution.......we are finishing a Unix/Linux program that blocks brute force attacks, even when those attacks are coming from multi proxy servers.
