Observations:
Many of these accounts have never had a withdraw. The coins appear to be for investment purposes only.
Some of the accounts are a few years old and have never been touched since leading one to wonder if the private key is lost or if they are in cold storage.
Tools like vanitygen or oclvanityminer (distributed client) could be used to recover the private keys and access these accounts with enough cpu power thrown at them.
