Maybe your name is the same as (or similar to) that of someone else who somehow got onto the list.
Let's say your name were something generic like "John Smith." Among the hundreds of other John Smiths, one might have somehow gotten on the list, causing undeserved trouble for all the other John Smiths whenever they fly.
Thought about this too. But with my name I figured it would've happened long ago. :-)
My name is fairly generic and I've gotten on the list (and no, it doesn't look anything like an Arabic name.) I always assumed it was just because I was posting to Free Republic and so I must be some sort of questionable character.
