Why is a potential guest being asked to upload a credit card statement?

They wouldn't be. Why do you feel they have?

It seems that people are being asked to do that, @Helen3. See this thread: https://community.airbnb.com/t5/Community-Help/Credit-Card-verification/m-p/287467/highlight/true#M3...

It was the first I had heard of it.

Must be to prove they are using their own card? 

You could suggest that this might be the case, @Tracy80.

I thi k they have been suffering a lot of CC fraud with stolen cards.
