I withdrew my money from BitMit (luckily it was only 1.2743 BTC) but I made that mistake I've been seeing people make. I was in a hurry and pulled an address from my address book rather than clicking receive coins. I have no idea what the address is. I made no contact with anybody during that time, whether through email or otherwise. It could possibly be a wallet that was on my phone, but I have no idea.
And that's why you should use labels on addresses lol

Address first used (2011-08-08). Maybe an account at some site? GLBSE? An exchange?
