I've used privacy.com mostly for entertainment purposes. It is 100% likely to be a honeypot. But used properly with a separate bank account that you only transfer money to when you need it there, it can be quite useful. Setup a credit card that is vendor locked and/or limited total charges, or limited per period charges, or even make it valid only for the first vendor to charge it. And close down the new, CC anytime you want. Plus, it has the added bonus of allowing *any* name to be used at the merchant.

The entertainment can happen if you are buying from someone that seems a bit dicey, but have no other source for what you want. So you buy from them and laugh like a hyena when a month later a couple of attempts to charge the now closed card pop up from India.

[I did a little digging when I first found it and was entirely unsurprised to find they are located in...Chinatown.]

In this particular situation, you can create a new CC in your privacy.com account and set the limit to, oh, $5. Change your payment method to that new card, and then immediately close it after authorization. Amazing how quickly a spurned vendor will *contact you* when your payment method no longer works.
