A date alone isn't an unquoted name; an image under a post token keys by the post

- "Ballers.2014.S01E01.HDTV.x264-KILLERS[ettv] 15_07_2015.rar", "Computer Bild
  - Ausgabe 152015 - 15_07_2015.rar": the cut after "] " or " - " left
  "15_07_2015.rar" for every item of a Razor1911 dump (1,335 files for 12);
  a date alone after the cut means the whole text is the name.
- "MDG005b - (01/90) "IMG_2307.JPG"": a counter in parentheses makes no post
  key, so every "IMG" set of the poster was one (609 for 90); an image under
  a post token is keyed by it too.
