So I deposited some Eth to Wex.nz exchange the other day to test and it got moved over to this address:

https://etherscan.io/address/0xb3aaaae47070264f3595c5032ee94b620a583a39

Which, by the comments, appears to be one of those "send your Ether here and we'll double it" scams.

Draw your own conclusions.
