Pictures are not an accurate portrayal of who that person is right now.
The hypothesis of women’s profiles being fake is clear when you look at the amount of dates which go horribly wrong. Women post pictures which are of the thinner version of themselves, the best possible angle, loads of filters, younger version of themselves, themselves in the midst of loads of friends, etc. Women are so concerned in making themselves look better than they currently are as opposed to how they are naturally now – as this is what the man will see when they go on a date.
Video profile on the other hand make dating super easy, as you both know each other quite well before meeting for the date. This makes the date focused on more interesting stuff.
