Thanks for the response Burt and Zip.
Yes Burt I read the downloaded php code and it looks clean and allows those good bots so they don't get blocked.
Also used the test procedure and it works on my server.
Visit this site twice...
https://nsgames.com.au/blackhole/
which is the page a bot would follow blindly into if the header and footer were on my pages if it ignores robots.txt a regular user would ..never.. see the links in the header/footer.
BTW its just a test so you can still see the site (I need those modules for the trap)
Although I'm not happy with the block message, I'm sure there would be a way to unblock the Contact_us page (which would be blocked if I had the modules) so a blocked IP if ..ever.. got trapped would not need a proxy and be a link to it there so a real user could send an email request.
I looked at the Phoenix tutorial to add a module for a footer kindly supplied in the Phoenix forums.
But it seems to need a header and footer module and I'm not a coder, I'm sure I can work it out over time.
As it seems relatively easy, I just don't have time and I'm old, and a little confused where/how to put
I will remove your bans after a bit, until I can work out the footer/header code to automate it, then ..bad Luck.

you will need to send an email..

This is the bit I can't do: or maybe I can, I don't know.
Step 4: Include the Blackhole script by adding the following line to the top of your pages (e.g., header.php):
<?php include(realpath(getenv('DOCUMENT_ROOT')) . '/blackhole/index.php'); ?>
The Blackhole script checks the bot’s IP address against the blacklist data file. If a match is found, the request is blocked with a customizable message.
Step 5: Add a hidden link to the /blackhole/ directory in the footer of your site’s web pages (replace “Your Site Name” with the name of your site):
<a rel="nofollow" style="display:none" href="
https://example.com/blackhole/" title="Do NOT follow this link or you will be banned from the site!">Your Site Name</a>
This is the hidden trigger link that bad bots will follow. It’s currently hidden with CSS, so 99.999% of visitors won’t ever see it. Alternately, to hide the link from users without relying on CSS, replace the anchor text with a transparent 1-pixel GIF image. For example:
<a rel="nofollow" style="display:none" href="
http://example.com/blackhole/" title="Do NOT follow this link or you will be banned from the site!"><img src="/images/1px.gif" alt=""></a>
Remember to edit the link href value and the image src to match the correct locations on your server.
