Snuff films are, fortunately, still only a subject of urban legends, since those films you mention do not meet the definition. Were those films made
in order to entertain other people than the person who made them? Were the films ever
distributed to any of those people? Was anyone ever actually killed
in any of these movies? If the answer to
any one of those three questions is “no”, then the movies, horrible as they may be, were
not “snuff” films, as commonly defined. From what I can see in your reference, the first
two of those things are decidedly
not true, and the reference is unclear regarding the third.
(The films were, according to your reference, made only for blackmail purposes, and therefore certainly not made for enjoyment of any viewer, nor were they ever distributed to other people for their enjoyment. The reference does claim that people were killed in a specific place which was also filmed, but does not, what I can see, explicitly state that any murders were actually filmed, other than incorrectly calling all the films “snuff” films.)
