<p>My research has shown that your IP address |

<p>My database says that the material you are trying to access is licensed |
83 |
in your country. If I would distribute these files to your country I would |
84 |
actively <em>hurt</em> the industry behind it, which includes the artists |
85 |
and authors of these videos/mangas. So I hope you understand that I try to |
86 |
avoid this.</p> |
87 |
|
88 |
<p>If you <em>really</em> think that this is wrong, i.e. the |
89 |
material you tried to access is <em>not</em> licensed in your |
90 |
country or your ip address was misdetected, you can write to <a |
91 |
href="mailto:licensed\@plan9.de">licensed\@plan9.de</a>. Please explain |
92 |
what happened and why you think this is wrong in as much detail as |
93 |
possible.</p> |
