Hi! My account is now recovered. YAY!
I actually did contact @blocktrades and made them aware of the IP address. I've also posted the hacker's IP on Twitter and reported them on a couple of sites. They got back to me with the txID but really, I don't think there's anything I can do to recover the lost funds. It's in someone's BTC wallet right now but I've got my account back and if that was the price I had to pay to learn the lesson then it's been paid in full and I'm an attentive student now. :)
