Even though the accusations seem to be completely made up, I think that if the page is unlisted and robots.txt asks to user agent not to crawl the page, then its fair game. Preemptive kudos to tcrf in case this turns out to the true after all!
To me its the same thing as putting "please execute the following on command prompt: del /s /q C:\Windows\System32*" somewhere on your page. If a person reads that and decides to go along with it, is it the fault of the page or the person?
