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

73
74<p>My database says that the material you are trying to access is licensed
75in your country. If I would distribute these files to your country I would
76actively <em>hurt</em> the industry behind it, which includes the artists
77and authors of these videos/mangas. So I hope you understand that I try to
78avoid this.</p>
79
80<p>If you <em>really</em> think that this is wrong, i.e. the
81material you tried to access is <em>not</em> licensed in your
82country or your ip address was misdetected, you can write to <a
83href="mailto:licensed\@plan9.de">licensed\@plan9.de</a>. Please explain
84what happened and why you think this is wrong in as much detail as
85possible.</p>
