The amendment further confuses me, because last I heard, credit cards reject gambling transactions from the United States. And most off-shore gambling sites use an intermediary to handle banking transactions. And I believe these intermediaries, such as Neteller, service other "vice" sites besides gambling (i.e. porn). So while I would speculate gambling is 95%+ of Neteller's business, I think there is enough plausible deniability regarding transactions with them, that I don't know you could cut off all bank ties with them. It's a distinction between vices which is reminiscent of Homer's line, when asked, after a car accident, what type of establishment this Moe's was from which he was coming home. If a bank ever denies your Neteller transaction, just remember Homer's response, and when asked why you were transferring $100 to a business identified as "Paradise," explain in as blase a voice as you can manage,"It's a pornography website! I was purchasing pornography." How can they argue with that.
In any event, I guess I should be glad it's unregulated. Once the government takes their cut, the rakes will no doubt go up.
