That site is pretty funny, but I'm wondering if those stories on buttcoin.org are completely made up. Myself and others have done several large withdrawals successfully from cavirtex--never had a problem. In fact, the only problem I've ever had was getting money in to the exchange. In Vancouver we have an active 'local bitcoins' community too; if you'd take a 10-15% discount to cavirtex, you could sell $100,000 tomorrow for cash.
