How can I find out if someone is using Facebook Dating?

To find out if someone is using Facebook Dating, you would typically need access to their Facebook account since the dating feature functions within the confines of a user's privacy settings. Facebook Dating doesn't make a user's activity on the feature public to their friends or family on the social network, ensuring that interactions remain private from their main Facebook profile. However, if you have an active Facebook Dating profile yourself, you could potentially come across their profile if they fit into your preferred match criteria and vice versa. But without direct confirmation or evidence from the person's account, determining whether someone is actively using Facebook Dating can be challenging due to its privacy-centric design.
