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

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

79actively <em>hurt</em> the industry behind it, which includes the artists
80and authors of these videos/mangas. So I hope you understand that I try to
81avoid this.</p>

86<p>If you <em>really</em> think that this is wrong, i.e. the
87material you tried to access is <em>not</em> licensed in your
88country or your ip address was misdetected, you can write to <a
