This could be just a box in the Iranian government's network which got hacked and hijacked into serving warez.

I once worked as sysadmin in a brazilian university, and it was quite common to stumble on unmaintained and hacked boxes serving warez or movies via FTP with dir hierarchies like /path/to/ftp/root/--==tagged-by-this-group==--/--==uploaded-by-that-group==--/warez/.
