An earlier investment that I actually got the BTC back was paid in transaction where two of the three input addresses are directly connected to address https://blockchain.info/address/1ADsF1KW8o9Qs1dty4oQJqvkjG94Qrc5T1 

BTC was also moved from this address to pay forum members for their signature ads, see e.g. transaction https://blockchain.info/tx/a3ae8463b554ecdd24c467ee2a010f5b0af26ab65fa54be7b5176ca872f8473c . This is the payment from post
https://bitcointalk.org/index.php?topic=303230.msg3279202#msg3279202 , the input is linked to 1ADsF1... via 1LPGkvLv52qrvS7HMf1ZcjPVRX4qtj4yDs and the return address 1Jv59HVhfWgJgRePfjzAAGkKwDkLjidrxi also leads back to 1ADsF1...

None of this of course proves anything and I have no experience in this kind of analysis, but it might be useful to look into 1ADsF1KW8o9Qs1dty4oQJqvkjG94Qrc5T1 for more details. That address seems to be still active and is receiving payments from Cloudhashing (1ALA5v7h49QT7WYLcRsxcXqXUqEqaWmkvw)
