Over the years we've got quite a bit spam on how to buy bitcoins with credit cards.
I'd like to have a more permanent solution in place instead of a clutter of different questions and answers, and this coming up every now and then, e.g. Buy bitcoins with my regular AMEX (american express card)
1) Should we have and maintain a list of services that allow such a thing in form of a canonical question and answer pair?
2) Should we close such questions as off-topic under the "product and service recommendation policy"?
