Many people are blocking HHTrack because idiots think because they "paid for
the files" that they may be entitled to the entire website.  Also, even "if"
you are just plugging into files that you do have access to, remember that a
mass download can resemble an attack to a website operator.  Don't be abusive
even if you think you are entitled.  It leads to sites closing permanently as
the owners get tired of the BS.  So what happens is the whole world looses the
resource.
