I agree, I had the same thought. And not only is she very pretty, she's also "believably pretty"; she doesn't look like a movie star or an unrealistically attractive Instagram model, she looks like someone you could see walking down the street. She'd catch your eye, of course, and probably be the prettiest person you saw that day, but it's not like some pictures/videos I've seen of people where I've thought "I've never seen someone look that attractive in real life" and there's a bit of a disconnect because of it.

Using Olga's likeness, I suspect a lot of people can be fooled into thinking she's just a regular person who happens to be at the upper end of the attractiveness scale rather than a paid model, and I'm sure they very intentionally decided to steal her likeness for that reason.
