If you can password-protect the pages, why not do that but include the
password in the text so that any human can see it and copy it?  i.e.

~~~~~~~~
To prove you are human you must type in the password, the password is
ABC   
Password: ___

~~~~~~~~

I don't think there is an easy way of writing anything automatic in the
HTML Body text but you might be able to add a script to the Head that
checks the IP address and blocks the ones you don't want.

If you can write PHP, you could easily write your own version of Captcha
or write a script that limits the number of repeat visits from the same
IP address in a given time.  Mixing PHP into HTML pages is easy but you
have to change the file extension of each page from  .htm  to   .php

Servers generally have facilities for PHP already built-in and the W3
Schools tutorials can get you started.
