This had me worried because there have been 1,054 bitcoins sent to it since the hacker withdrew the bulk of the funds.
However, it's mostly due to three transactions where 699, 86, and 75 bitcoins were sent to it. The other ~200 bitcoins were from small deposits.
A twitter user complained he had an arrangement for someone to send bitcoins to his bitstamp address which he could not cancel. I expect others may have been in his position, and there must still be people who have not heard about the hack.
