There is a unique link validator out there that may be of interest to
webmasters who need help to maintain their sites.

It can be reviewed and downloaded at :

The following is a description of what it does:

If your web site has links to external web pages, then they may be, at
any time, made to point to inappropriate content that is often adult
in nature. How does this happen? If a company allows its rights to its
domain name to lapse, even briefly, then cyberpirates can snap it up
and then make the address point to new content of their choosing. They
do this to drive traffic to their websites, the practice is common and
is called "porn-napping".

If you had been using XShield, it is not likely that you would be
finding this out from an angry customer email. Instead you could have
been monitoring the status of your links and XShield could have
alerted you to any content changes that were inappropriate. XShield
can scan automatically in the background throughout the day and even
send automatic email alerts to your IT personnel to enable a quick
response to any problems that may develop.
