… but I've just noticed some people on the .com have a little "badge" on their customer reviews.
I've seen the "top n reviewer" ones. This one is new to me: "real name" and means that the user name is – gasp – their real name. (To be more precise, the name on a credit card, which is apparently the same thing.)
What drew my attention to it was that it actually says is "REAL NAMETM".
Yep, Amazon are claiming a trademark on "real name".
