@Sharyn5 Exactly. I couldn't care less if a guest is attractive or ugly, fat or thin, what color their skin is, their sexual orientation, their religion, their nationality.
But the way someone presents themselves when expecting to be accepted into private homes says a lot about them. If they can't understand the difference between the appropriateness of an impression they are giving with a sexy, scantily clad photo on Instagram and that being something hosts will be okay with, there's likely other inappropriate behaviors they will think are fine.
Hosts have gotten photos with the guest holding a gun, giving a finger to the camera, looking totally wasted at a party, sitting in a chair with Hooters girls draped all over them. Uh-uh. No way am I hosting you.
