For one, you can't log in over Tor. They block all known tor IP's, so unless you are exceedingly lucky and happen to hit a very new relay, you can't get in to your account.I'm looking into it myself, more for pricing consistency purposes. BTC have dropped off 20% since since a bunch of my orders were in and they just cleared escrow at a pretty stiff discount. That margin of mine, it's gone! Hazard of the trade, though.
