I go into the bank at 10 o'clock, go, "Hi, I'm Dave Birch, I've got a 3 o'clock with so and so there." Sure. They sign me in. There's my visitor's badge. So this nonsense about you've got to have real names on Facebook and whatever, that gets you that kind of security.
Llego puntual y digo, "Hola, soy Dave Birch, tengo cita con fulano de tal". Seguro. Me registran. Me dan mi distintivo de visitante. No tiene sentido tener nombres reales en Facebook o lo que sea, que nos den ese tipo de seguridad.
