blackhole page indexed buy google.

Google and other major search engines are whitelisted and never will be blocked by the plugin. What you are seeing there is that Google somehow managed to:

– Disregard your robots.txt file
– Disregard the nofollow attribute on the trigger link
– Disregard the noindex/noarchive on the blackhole page

Another thing to keep in mind is that the plugin does not work when any Page Cache type plugin is active on the same site. Check the plugin docs for more details. Or if you have any further questions feel free to post again. Thank you
