Presumably Tinder would benefit then from a rating system (it may already have one - I am not in that social milieu).

If one wants to have Tinder Hot badge you need to go on five dates and be rated 5 stars for each. You would be signalling you are attractive and others think so. (I expect this is already done through some count or left / right swipe ratio)

(I can see that leading to some horrible coercion issues so I would oppose it but you get this idea)
