What does it mean if a user has no feedback?

Hi! (again)
So many users of Numista have no feedback but like 10,000 coins to swap, and they don't have the little above their name.
I'm swapping with someone and they have no feedback, why?
Thanks,
Larry

One word: "Be careful!"

And the best tip I received when starting to swap, try to find reputable swappers to start with and build up your own reputation by sending first.

It means that the member involved just hasn't completed a swap yet.

Also, always check when the account was created. There are many scammers who filles their swap lists, and the account is just a day or two old. Some also try to be smart, and creates many accounts to give each other positive feedbacks, so always check the most recent feedbacks, and check when the accounts was created. To have feedback from a 1 day old accounts, means that the swap was aggreed on and finalised before the account was created. Be aware of these!
