Ok, I haven't been online in a while but I definitely got a double deposit (0.1 BTC, didn't keep reserves with the glbse), but I haven't gotten an e-mail stating that I did get a double deposit so this is the first I am hearing about. Without an e-mail saying I should give it back, I will wait for further instructions.
Look here:
So, for anyone reading this who has gotten a double payment, the return address is 1BgPRMk4uaJrohM1T9Cn4Hd9pHaEL6FH5j
But wait...
Judging from
http://blockchain.info/address/1BgPRMk4uaJrohM1T9Cn4Hd9pHaEL6FH5j, Nefario just (a 2 confirmations ago) have started some moves with BTC from this address.
Is he going to make the final payouts now?
Looks like nothing moves again.
