I have 1 order I don't have any idea who it came from, amount sent was ~10 BTC
Yes, it's a strange problem we sometimes have with our Version 1 site combined with the success we've had.
One time we even had a lady or gentleman place an order in before we had the GB round offering ready.
Before we were ready to list it on the forums, we only had the mfg., hashrate, and price listed in the title, with a site description that literally said: "Placeholder text" and he sent us a payment for some shares. That was a first and a source of some surprise and amusement that someone would trust us to fill in the blanks later.
