Which exchanges are Tor-friendly? Mt. Gox's sign-up page states:


  Please be advised that accessing your account via the Tor network
  and/or public proxies may result in a temporary suspension of your
  account, and having to submit AML documents.


Are there other exchanges which do not have such a restriction (e.g. for transfers and account balances below $1K USD for instance?)
BitInstant seems like a nice Tor-friendly option (they even accept deposits in cash): https://www.bitinstant.com/
