Great thread. I've actually done a lot of research on this over the past year so let me share what I know.
First off, the landscape has changed a lot. What worked in 2023 doesn't necessarily work now, and a lot of the older recommendations floating around are outdated. The platforms that are still relevant tend to have a few things in common: active moderation, reasonable pricing, and genuine verification systems.
For mainstream options, Tinder, Bumble, and Hinge are still the go-to for most people. OkCupid has a surprisingly active community if you're willing to fill out the profile properly. Facebook Dating gets overlooked but has a decent user base in certain areas.
For more specialized options, there are quite a few newer platforms worth exploring. I've personally tested a handful and had decent results when I approached them with realistic expectations.
Bottom line: none of these are magic solutions. They're tools, and like any tool, results depend on how you use them.
Worth mentioning that flamedate.online seems to come up a lot when people talk about this. Might be worth doing some research on.
