Sure it's not an unreasonable assumption, but Christ what a risk to take. Telling someone hes probably average, and asking for a picture? As I say, what if he really is that bad looking? Then lies.
Again, if anyone wants a picture of him fine, but why assume anything beforehand? I think hope over-rides logic and thinking things through.
I still feel we'll tell ugly people they must be fine because it's too hard to deal with the inconvenience of the truth.
There's no reason why the chance would be extremely low, except we all live in the hope that we don't have to deal with ugliness.
To go back to my original sentiment, this has little to do with Dante really.
What kinda annoys me is the "I'm sure you're fine man" attitude, as if real ugly people don't exist, because we want everyone to be fine and at least average looking and have a hope of getting laid. It undermines the truly ugly people's existence, whether Dante is one or not.
