Interesting indeed and no idea what is going on there, why do people keep sending money to it? The last transaction was sent yesterday and the address who sent the coins yesterday seems to be including that address in all of the transactions. Very odd.. There's more than 3 Bitcoins there right now and by today's price that would be around $700 and if no one ever finds the key to that address (which no one will) that's $700 just thrown away for no reason??
Also, what's with this message "Unable to decode output address" every transaction shows that, what does it mean?
