Read the ciphertext. Strip whitespace: 3,600 hex characters = 1,800 bytes = 225 8-byte 3DES blocks.
Derive the key. Password = A858DE45F56D9BC9 (name). Key = MD5(password) = 34a14a42e98ff96095af56604e290cae, used as a two-key 3DES key.
Decrypt. 3DES-EDE2 in ECB mode, then strip the PKCS7 padding. The plaintext is 56 GUIDs as hex (shown below).

Explanation

Explain the mask digits. The version nibble (13th hex digit) of each GUID, read in order, gives 41888544116104484441858545302710811727040000208481117628. Exactly this sequence comes out of new Random(325).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 jan2013-A2: piece A (second instance from Jan 9, daily, zone -5), 7 posts at range 8: undecidable, all boot hypotheses chance-level
Conclusion. Filler. The content is fully explained by the two RNGs.
