Explanation

  1. Read the length. 400 hex characters = 64 × 6 + 16, i.e. N = 6 GUIDs encrypted with 3DES plus one 8-byte padding block. Every post-cutover filler post has exactly this shape.
  2. Key unknown. The post-cutover key (2013-10-16 onwards) has not been found, so the GUIDs themselves cannot be read. Everything else about the post is accounted for.
  3. Explain the count. This post is draw 74 of Run 60 (seed 19,858,187): new Random(19858187), Next(0,50) per post. The RNG predicts N = 6; the post has N = 6 ✓. The seed is the machine's uptime in ms when the app started (boot 2014-03-12 08:29–10:29).
  4. Conclusion. Filler. Structure and count are explained; the GUIDs are presumed filler like every decrypted post before the cutover.
