That's why Twitpay didn't go the "put funds into your account" model. We're powered by Amazon Payments, and to settle up and move actual dollars requires logging in to Amazon and approving the transaction. We're actually one of the more vocal critics of the "give out your Twitter password to any and all services", so we designed Twitpay to avoid the issues around that.
