Read the ciphertext. Strip whitespace: 4,112 hex characters = 2,056 bytes = 257 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 64 GUIDs as hex (shown below).

Explanation

Explain the mask digits. The version nibble (13th hex digit) of each GUID, read in order, gives 0336642854261425063806523512456414757233662228815026451371203048. Exactly this sequence comes out of new Random(619).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. Part of Fixed N=64 (Dec 2012 - Jan 2013): an app start that posted N = 64 every time.
Conclusion. Filler. The content is fully explained by the two RNGs.
