I pay ~$10 for membership on a niche dating website (for a community that is not served well by the likes of Tinder / Match.com / etc.). The emphasis is on meeting IRL, and the biggest problem they solve is to offer a large and dense (geographically speaking) network of like-minded real people who are ready to meet. Paid subscription is not the only trick they use to weed out fakes, but it goes a long way. Money is pretty much the only constraint that keeps the site from being flooded by bots and spams.
