I wasn't making any purchase. Hadn't tried to back order any domain. I hadn't even done a search for a domain name. I can only presume that they intended to store the CVC number.
This isn't a small back order company. It is a large, well known company. One that is also tied to a large (very large) domain registrar.
Has anyone else run into this and thought it was contrary to Visa and MasterCard contracts? If anyone in the know reads this, are they actually storing that CVC?
I sent an email to them asking if/why they were collecting the CVC, but I have not yet received any reply.
[I am assuming that it is not okay to mention the actual name of the company. Webwork - if it is okay please say so and I will post the name as that might help]
So they must be storing it too or they required it to validate the other new details.
Also, I didn't mention in my original post that I tried entering a bogus CVC number and it was rejected. So they are definitely doing this at a minimum. (I don't think that there is a transaction type just for verifying a card)
I still haven't gotten a response back from them - If/when I do receive one I will post any relevant information.
Thanks for everyone's input.
