It's not a random mix of letters and numbers.

It looks like a genuine first/last name separated in one case by "." and the other case by "-".

I just didnt put the real names up here in my original post becasue that is a bit of a non-no on the boards.

***EDIT***

Oh and by the way there has been no payment on either purchase yet and no answer to my question to please clarify.

I am tending to think its a new buyer who simply has NFI what they are doing.
