If this guy is the only one changing his content, what I would do is run
a trivial script on a remote machine: every day (or whatever) fetch the
entire content of the site (with wget) compare (with cmp) the new content
to the previous content, and finally email or SMS this guy the number of
modified files. If he knows that he modified one page, and got a mail saying
one page changed, he's safe. If he changed nothing and got a message that
100 pages changed, he knows he has a big problem.
I don't think that "scanning for porn links" will work; How will you know
that these are porn links? And what will happen the next time his site is
cracked, and the cracker won't add porn links, but do something else?

During the doc.com boom, I remember an Israeli startup whose business was
exactly this - noticing that a site has been defaced using remote servers
which constantly try to download pages from the site and notice if something
has changed. Unfortunately, I can't recall now the company's name.
