One great feature of Privacy.com is that you can use pseudonyms rather than your legal name for making purchases. One "failure" mode I've encountered (twice!) is that if you accidentally reuse an old credit card account with a second service (eg. if you accidentally created a card for "donations" and use it at two different websites, or you create one for Ko-Fi or similar and it gets charged by multiple different "merchants" under the same service), the second transaction will fail. You'll get an email telling you the transaction was declined, but if you don't have email notifications enabled, it can get quite confusing why the payment isn't going through.
