Explanation

  1. Read the length. 208 hex characters = 64 × 3 + 16, i.e. N = 3 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 1 of Run 67 (seed 466,795,333): new Random(466795333), Next(0,25) +2 per post. The RNG predicts N = 3; the post has N = 3 ✓. The seed is the machine's uptime in ms when the app started (boot 2015-08-13 10:08–11:01).
  4. Conclusion. Filler. Structure and count are explained; the GUIDs are presumed filler like every decrypted post before the cutover.
