70<p>My research has shown that your IP address
71(<b>$self->{remote_addr}</b>) most probably is located in this country:
72<b>$country</b> (ISO-3166-2 code, XX == unknown). The full record is:</p>

77
78<p>My database says that the material you are trying to access is licensed
79in your country. If I would distribute these files to your country I would
80actively <em>hurt</em> the industry behind it, which includes the artists
81and authors of these videos/mangas. So I hope you understand that I try to
82avoid this.</p>
83
84<p>If you <em>really</em> think that this is wrong, i.e. the
85material you tried to access is <em>not</em> licensed in your
86country or your ip address was misdetected, you can write to <a
87href="mailto:licensed\@plan9.de">licensed\@plan9.de</a>. Please explain
88what happened and why you think this is wrong in as much detail as
89possible.</p>
