75 | <p>My database says that the material you are trying to access is licensed |

76 | in your country. If I would distribute these files to your country I would |
|
|
77 | actively <em>hurt</em> the industry behind it, which includes the artists |
|
|
78 | and authors of these videos/mangas. So I hope you understand that I try to |
|
|
79 | avoid this.</p> |

80 | |
|
|
81 | <p>If you <em>really</em> think that this is wrong, i.e. the |
|
|
82 | material you tried to access is <em>not</em> licensed in your |
|
|
83 | country or your ip address was misdetected, you can write to <a |
|
|
84 | href="mailto:licensed\@plan9.de">licensed\@plan9.de</a>. Please explain |
|
|
85 | what happened and why you think this is wrong in as much detail as |

|
86 | possible.</p> |
