This reminds me of joker[1], with the benefit of not expecting you to feed it a torrent (or expecting you to know what a torrent is).

I genuinely wonder, though, if these services are published just to annoy the copyright owners or for some benefit to the author that I sadly cannot see.

edit: They also do not seem to serve ads. Maybe an experiment for a potential legal version? Who knows...
