Read the ciphertext. Strip whitespace: 3,856 hex characters = 1,928 bytes = 241 8-byte 3DES blocks.
Derive the key. Password = A858DE45F56D9BC9201303232059 (name+title). Key = MD5(password) = aa0ee96dcfc40ca20d83b6cafeadcf55, 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 575887638573160674383278342068580040427563021058752221720643. Exactly this sequence comes out of new Random(283).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. This post is draw 4 of Run 43 (seed 120,022,078): new Random(120022078), 4·Next(8,16) per post. The RNG predicts N = 60; the post has N = 60 ✓. The seed is the machine's uptime in ms when the app started (boot 2013-03-21 09:44–10:39).
Conclusion. Filler. The content is fully explained by the two RNGs.
