Read the ciphertext. Strip whitespace: 3,856 hex characters = 1,928 bytes = 241 8-byte 3DES blocks.
Derive the key. Password = A858DE45F56D9BC9201304111656 (name+title). Key = MD5(password) = f64ffd9a251281eef6c8fa99d404f303, used as a two-key 3DES key.
Decrypt. 3DES-EDE2 in ECB mode, then strip the PKCS7 padding. The plaintext is 60 GUIDs as hex (shown below).

Explanation

Explain the mask digits. The version nibble (13th hex digit) of each GUID, read in order, gives 503773434064877248438242716471106171684874262488116018534085. Exactly this sequence comes out of new Random(287).Next(9): the per-post millisecond seed of the mask generator. The other 30 hex digits of each GUID are Guid.NewGuid() output and carry no message.
Explain the count. Grouped in 1c4e07: single scheduled post (04-11 06:57:00) under the previous run settings (title +9.98 h); N 60 = draw 95 of the previous 1bjynu process and draw 0 of the new 51,450,859 instance, so unplaced; the new run starts at 1c6pey (draw 1)
Conclusion. Filler. The content is fully explained by the two RNGs.
