Guest Book log infected?

[Police Cruiser]

Could someone please take a look at two guestbook's I have on two sites and
tell me how I can locate/prevent what appears to be an intrusion of posting
of porn and other website links in the guest log?

I have tried deleting the creating a new guest book page three times, each
time the SOB appears. I edit the guestlog and they still keep coming back.
The pages are http://www.roadknights.info/guest.htm and
http://www.peekskillmuseum.com/guestbook.htm . The museum guestbook appears
to be clean now. but the other will start messing up usually within one
hour.

Going CRAZY

Thanks.

There is nothing you can do about this when using the FrontPage
guestbook. When a spammer finds a guestbook, he will use it.

The solution is to use a different technology to build a guestbook,
such as ASP, asp.NET, PHP, Perl/CGI - whatever your server supports,
coupled with a suitable database to hold the posts. (A database can
be a single HTML page, or a full server application like mySQL, Ms
SQL, or something in-between like Access.)
This application can be made to vet posters, and remove any links they
include before the posts are posted.

In the interim, try changing the name of your guestbook - it may put
the spammers off for a few days, though will be inconvenient for your
regular users.
