I've recently tried to use WWW::Scraper::ISBN with the ISBNnu driver and noticed I wasn't getting _any_ results back. Some debugging showed the following:
=======
You have been blocked from using this site because either your machine or a machine on the same network - which might include other customers of an Internet Service Provider - are using a computer to methodically process ISBNs. This site is meant for individual consumer use, not for bulk extraction by busineses. Please contact the owner of this site, Glenn Fleishman, at comments [at] isbn.nu to regain access.
=======
The IP address has _not_ been blocked, as the site makes you belief. In fact, supplying LWP::Useragent with a semi-valid UserAgent string, will patch this hole in this driver, and will "restore" access:
my $ua = new LWP::UserAgent;
$ua->agent('Mozilla/5.0');
I would stongly suggest to contact the author of the website to discuss this further though. In the meanwhile either patch it like this or discontinue using this driver ;-)
