prevent sharing of logon information

[Jesse Aufiero]

What is the most sure-fire way to prevent users of my web site from sharing
their logon information with others? i want to guarantee that only paying
customers are allowed into the site.

Thanks

The only guaranteed way to prevent a person from sharing information
is by killing them, and even that is only a guarantee that they won't
share future information. Somehow I don't think you want to go that
far.

You could try monitoring the IP addresses associated with a login, and
warn a user that their account may be canceled when/if you start
seeing rapid access for vastly different IPs. (like more than 2
different ISPs in less than 5 minutes.) However, even that is no
guarantee of different users.
