Linking to bank account doesn't work, bank never shows up to allow a withdraw. Simply put I can't withdraw USD. As a US customer can't trade HNS for BTC. Can't transfer HNS to external wallet. As a result of all these issues funds are locked in namebase.io and can't be withdrew. I was able to sell HNS for USD. But that USD can't be used to buy HNS. I can only buy HNS by depositing new funds that would also result in getting stuck in namebase.io
