Has anyone checked this address?

https://blockchain.info/address/12Nxd2X12WZeYSjUcbtm5NpS3d81Yh8sKh

there are many transfers of 0.00777 BTC to addresses containing thousands of coins


The weird thing is that all these transfers occurred on Feb 6th before Mtgox suspended withdrawals


Another suspect thing is that this seems to be a mtgox customer. The following deposit and withdrawals from the leaked db seem to match exactly this address:

e9ceb1e2-0497-427b-aca0-4f8e6aa2018a,557fe7d5-e199-474f-a1c0-6b2d05d568ae,"2014-02-05 23:18:00",deposit,43.3
e9ceb1e2-0497-427b-aca0-4f8e6aa2018a,0d807f90-23a3-46d2-80d7-5c2addfda825,"2014-02-06 17:33:42",withdraw,-1


Any clue?
