I'm not sure whether the gift card deal actually took place or not. If you look at the thread, there was never someone confirming they have sent/received the 0.9 BTC brazilcoins was supposed to receive.
I see, just read through the thread (would have been better linking the first page/message by brazilcoin than the second one that starts with snuggles paranoia).
I don't get why they don't use escrows in those deals, but well, there's only so many times you can tell a user.
