He said "sent" at 2013-10-19 10:56:20 in UTC actual, and the TX broadcasted at 2013-10-19 13:33:46 UTC. If btc.sx manually processes withdrawals, that's about 2.5 hours before they approved it. And seeing a screenshot of starsoccer's account, 1CeygUifXfT4jRBTSV3tPQJnthyBL32eHT is his btc.sx deposit address, and 18fbVfNM5N1V4iDBR8bVcXzLZkWuJbxqkb (the address it was swept to) is apparently their cold wallet?
So did someone f up and direct his withdrawal right back to his own deposit address (WTF, how do you not realize that if you're site admin?) instead of 1TBZYXjrGjXCEN1SprpF66Jzy5uN3GiLS, which is what he said he put in the withdraw address box the first time? The screenshot he sent shows his second attempt to withdraw to 1TBZYX...
ETA: And what do you know,
https://blockchain.info/address/18fbVfNM5N1V4iDBR8bVcXzLZkWuJbxqkb just sent me 0.1. Was that the one he just resubmitted, or the one from the 19th? I guess I need to keep an eye out for the next few days to see if I get a duplicate 0.1... /facepalm
