Read the ciphertext. Strip whitespace: 3,664 hex characters = 1,832 bytes = 229 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 57 GUIDs as hex (shown below).

Explanation

Explain the mask digits. The version nibble (13th hex digit) of each GUID, read in order, gives 158171536843734422780775686764027512486383625145021114227. Exactly this sequence comes out of new Random(265).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 w2g3v: 4 hourly posts before runs 11/12; undecided: candidate seeds 70,597,546 / 2,764,093 on a new boot after run 10 stopped, 2 hits vs 0.51 expected; run 10 boot excluded
Conclusion. Filler. The content is fully explained by the two RNGs.
