Well - as the error states, the URL has been blocked. It does not appear to be related to your scripts.
Of course, if your scripts were doing strange things that Facebook didn't approve of, like violating their TOS, then they might have blocked your specific URL. I don't believe this is the case because you mentioned that you are using a free domain service - it would be conceivable that Facebook would want to block such "open" services in order to prevent possible security issues.
