You can read this in any product sheet or user's manual for any of the portals.

To be fair, it's not apparant to me that this is a "well-known fact" or common believe if people on this forum (and other sites and private conversations, etc.) are asking questions about the "random" selections process. I'm no road warrior (or air-warrior), but I am no neophyte to flying either, and this is the first I've heard of any feature of the WTMD "randomly" indicating selections for further actions for the TSA.
That being said, thank you for posting the information. Knowledge is everything (to me, anyway). And I'd prefer if something were truly random, rather than someone's "hottie alert" selection decision, etc.
