The one time I had a credit card number stolen, Wells Fargo noticed the problem before I did. When I asked their fraud guy what the charges were that I didn't make he said they were a couple of domain name registrations. Presumably attempting to register domains is something card thieves do to verify a stolen number actually works before they resell it or use it for "real" purchases... but why they use domain fees for this, I have no idea. Also, this was years ago, so one would assume that by now the card thieves have moved on to new methods that don't red flag so fast? Interestingly enough, none of my own real domain registration fees has ever tripped up a card block and I've owned dozens of domains over the years.
